Concussion Return to Play Protocol: The 6 Steps
If a season is on hold, or a clearance form is sitting on a kitchen table, the thing you're looking for is the concussion return to play protocol — the six-step graduated progression that moves an athlete from ordinary daily activity back to full competition, one stage at a time.
It isn't a waiting game, and it isn't a stretch of enforced rest. The old advice — sit in a dark room until everything clears — has been replaced. What's replaced it is a staged, symptom-guided sequence that a healthcare provider runs, watches and signs off on.
This page is the reference. The six steps, what each one involves, what has to be true before the next one starts, and who is allowed to make that call. It is education, not clearance — the clearance belongs to a clinician who has examined the athlete.
What is the return to play protocol, and where does it come from?
The return to play protocol is a six-step graduated return-to-sport strategy set out in the international consensus statement on concussion in sport, agreed at the 6th International Conference in Amsterdam and published in 2023. It runs from symptom-limited daily activity through to full competition, and it is followed under the supervision of a healthcare provider rather than self-administered.
The consensus is the document athletic trainers, team physicians and sports medicine clinics work from, which is why the wording of a school's protocol, a league's form and a clinic's handout tend to look so similar — they're all downstream of the same source. The steps run: symptom-limited activity, aerobic exercise (light, then moderate), individual sport-specific exercise, non-contact training drills, full-contact practice, and return to sport. Each step in the Amsterdam 2023 graduated return-to-sport strategy adds one thing: more intensity, more sport, more risk of contact.
Note what the protocol is not. It is not a diagnosis, it is not a treatment plan for symptoms that aren't settling, and it is not a calendar. It's a sequence, and the pace is set by the person supervising it.
When is a head injury an emergency rather than a protocol question?
Some head injuries need an emergency department the same hour, not a stepwise plan. In adults, the CDC lists danger signs including a headache that gets worse and does not go away, and losing consciousness, looking very drowsy or being impossible to wake.
In children, those same signs apply, and the CDC danger signs list adds two more that parents of small children should know by heart: a child who will not stop crying and cannot be consoled, and a child who will not nurse or eat. If any of those appear, the return-to-play conversation waits. Go to an emergency department. Our guide to concussion signs in babies and toddlers goes through what this looks like in children too young to describe a headache.
What are the six concussion protocol steps?
The six concussion protocol steps are symptom-limited activity, aerobic exercise, sport-specific exercise, non-contact training drills, full-contact practice, and return to sport. Each step has a different job, and an athlete only moves up when the supervising clinician judges the current step is being tolerated.
The table below is the full protocol in one place — what the athlete actually does at each step, why that step exists, and what has to be true before the next one. The right-hand column is the one people skip and the one that matters.
| Step | What the athlete does | The goal of the step | What has to be true to move on |
|---|---|---|---|
| 1. Symptom-limited activity | Ordinary daily life, kept below the level that clearly stirs symptoms up — walking, light household activity, screens and reading in short blocks, school work reintroduced gradually. | Get normal daily activity back without provoking a flare. This is the baseline everything else is built on. | Daily routine and school or work demands are being handled, and the clinician supervising the protocol judges the athlete ready for structured exercise. |
| 2. Aerobic exercise (2A light, then 2B moderate) | 2A: walking or stationary cycling at a light pace. 2B: the same modes at a moderate pace. Exercise only — no resistance training, no drills, no equipment, no teammates. | Raise the heart rate deliberately and stay below the intensity at which symptoms come on. This is the step that does the most work. | The intensity is tolerated, and the provider steps it up — light to moderate first, then on to sport movement. An exercise tolerance test may be used here to set the ceiling. |
| 3. Individual sport-specific exercise | Running, skating, throwing, shooting, footwork — the movements of the actual sport, performed alone, with no possibility of head impact. | Add speed, direction changes and sport-specific movement on top of a heart rate the athlete already tolerates. | Sport movement is tolerated at intensity, still with zero contact, and the supervising clinician clears the athlete into team-based drills. |
| 4. Non-contact training drills | Team training drills, passing and tactical work, more complex patterns; resistance training can be reintroduced at this stage. | Combine exertion, coordination and decision-making under load — thinking and moving fast at the same time. | The athlete completes full non-contact training without a setback, and has provider approval before anything with contact in it begins. This is the gate, not step 6. |
| 5. Full-contact practice | Normal training, contact included, in the practice environment rather than competition. | Restore confidence and let coaching and medical staff watch the athlete under real conditions before a game counts. | Medical clearance is in hand before this step starts, and the practice is completed under supervision without symptoms returning. |
| 6. Return to sport | Full competition, no restrictions. | Normal participation. | Full-contact practice has been tolerated and the healthcare provider's approval stands. If the school or league requires a written clearance form, it is signed at this point, not assumed. |
How long does each step take, and what if symptoms come back?
There is no honest per-step number we can give you, because the pace belongs to the clinician supervising the athlete and depends on age, symptom burden and concussion history. What is consistent is the principle: if symptoms return at a step, that step is too much, and the athlete drops back to a level that was tolerated before trying again.
Two things are worth knowing about the wider clock. Symptoms are generally called persisting beyond two weeks in adults and beyond four weeks in children, and up to 30% of children and adolescents are still symptomatic at four weeks or longer, according to the pediatric companion paper to the Amsterdam consensus. A protocol that stalls is common, and it is not evidence that an athlete is malingering or unfit. If it stalls, the answer is an assessment, not another week of waiting — our guide to symptoms that persist past the expected window covers what that assessment usually involves, and the stages of concussion recovery explains how the medical picture and the sport protocol run alongside each other.
Is there a return to play protocol concussion PDF to print?
We don't publish a PDF, and we won't pretend one exists — but this page is built to be the printable reference, and the table above is complete. Print it straight from your browser with Ctrl+P or Cmd+P and take it to a coach, an athletic trainer or a school nurse.
If someone hands you an "official" printable protocol, check where it came from. The one that matters for a specific athlete is the one issued by the provider managing that athlete, or by the school district or governing body whose form has to be signed. A generic printout is useful for understanding the sequence and useless as a clearance document.
What has to happen before an athlete reaches step 6?
Before full return to sport, an athlete needs the approval of a healthcare provider and has to be progressing under that provider's supervision — the CDC states this plainly for return to sports practices, which means the approval is needed well before competition. That approval is not a formality issued at the end; it is what allows contact steps to happen at all.
In practice, the sequence is: everyday activity, exercise, sport movement, non-contact drills, then a clinician's decision, then contact. The CDC HEADS UP guidance on returning to sports is explicit that an athlete should only return to sports practices with the approval and under the supervision of their healthcare provider. Nothing on this page substitutes for that, and no coach, parent, teammate or website is a substitute for it either.
What is the return to learn protocol, and why does school come before sport?
The return to learn protocol is a separate four-step strategy in the same consensus, running from relative rest, to gradual reintroduction of school work, to part-time school, to full-time school. It is handled first because the classroom is the lower-risk environment and because an athlete who can't yet manage a school day isn't in a position to manage a contact practice.
The expectation for school is faster than most families assume. The CDC's position is that most children can return to school within 1 to 2 days of a concussion, with accommodations as needed — shortened days, reduced screen work, extra time, breaks. That is a very different picture from being kept home for a fortnight, and it is one of the clearest places where the current guidance has moved away from what parents were told a decade ago. School participation is being rebuilt while the early steps of the sport protocol are underway, not afterwards.
Can you exercise at all in the first 48 hours?
Yes — light-intensity physical activity is appropriate during the first 24 to 48 hours after a concussion, according to the Amsterdam consensus. Complete rest for days on end is no longer the recommendation, and that change is the single biggest practical difference between current guidance and the advice most people remember.
Light-intensity means walking, gentle movement, everyday activity that doesn't meaningfully worsen how the athlete feels. It does not mean training, and it does not mean starting step 2 on day one. The consensus statement's guidance on early activity is that individuals can return to light-intensity physical activity during those initial 24 to 48 hours — which is permission to move, not permission to train.
Why does early aerobic exercise below the symptom threshold matter?
Because there is trial evidence that it shortens recovery rather than risking it. In a 2019 randomized clinical trial, participants prescribed individualized sub-threshold aerobic exercise recovered in a median of 13 days, while participants given a stretching program recovered in 17.
That result — from a trial published in JAMA Pediatrics on early sub-threshold aerobic exercise — is a group median, not a promise about any one athlete, and it doesn't mean more exercise is better. The word doing the work is sub-threshold: exercise deliberately kept under the intensity at which symptoms appear. Above that line, the athlete is provoking symptoms. Below it, the exercise is the intervention.
How is the exercise threshold actually set?
With a supervised exercise tolerance test. The Buffalo Concussion Treadmill Test (BCTT) is the most widely used of these: it identifies the heart rate threshold of exercise tolerance in concussed patients, which then becomes the ceiling for step 2 work.
The test is described in its own 2019 paper on exercise tolerance after concussion, separate from the trial above. In a clinic setting it's a graded treadmill protocol run under observation, with symptoms and heart rate tracked as the workload rises, and the point at which symptoms increase defines the threshold. This is exactly the sort of thing that can't be improvised at home or estimated from a fitness watch, and it's a good example of what a sports concussion program adds over a generic sign-off.
Who can clear an athlete, and how do you find them?
Clearance comes from a healthcare provider with concussion training — commonly a sports medicine physician, a neurologist, a rehabilitation physician, or a clinician working alongside a certified athletic trainer. Many schools and clubs have that relationship already; if yours doesn't, you're looking for a clinic that explicitly runs return-to-play and return-to-learn programs.
Across the 3,205 verified listings in our directory, 1,413 are tagged for Return to Play/Learn and 1,453 serve athletes and sports populations, including 222 sports medicine groups. Those return-to-play listings sit in 44 states — not all 50 states and DC that the directory covers, and it's worth saying so plainly rather than implying a clinic is around every corner. If you're not sure which type of clinician the athlete actually needs, the two-minute specialist matcher narrows it down before you start phoning.
If the athlete in front of you is stuck between steps, has symptoms that aren't settling, or has a form that nobody local will sign, the next move is a clinician who does this work routinely. Search verified concussion clinics by state and city to find programs that list return-to-play and return-to-learn among their services, then call and ask directly whether they supervise graduated return-to-sport progressions and issue clearance. That one question will sort the list quickly.
If you are the clinician or athletic trainer on the other side of that call — the one signing the forms — and your program isn't in the directory yet, you can get your clinic listed. Inclusion is free and every listing is verified against your own public website.

Frequently asked questions
Can an athlete go back the same day as a suspected concussion?
Return to sport happens only with the approval and under the supervision of a healthcare provider, so it isn't a call a coach, parent or athlete makes on the sideline. The graduated strategy also puts several non-contact steps ahead of any contact, and provider approval is required before the contact steps begin.
What's the difference between the return to play and return to learn protocols?
Return to play is the six-step graduated return-to-sport strategy, ending in full competition. Return to learn is a separate four-step strategy in the same consensus — relative rest, gradual reintroduction of school work, part-time school, then full-time school — and the classroom is rebuilt first because it is the lower-risk environment.
Does an athlete have to be completely symptom-free before starting the protocol?
No — the first step is symptom-limited activity, not total rest, and the consensus supports light-intensity physical activity during the first 24 to 48 hours after a concussion. What the steps are built around is staying below the level that clearly provokes symptoms, with the supervising clinician setting the pace.
Is the protocol different for children and teenagers?
The six-step structure is the same, but children and adolescents are managed more cautiously, and school comes before sport. Up to 30% of children and adolescents still have symptoms at four weeks or longer, according to the pediatric companion paper to the Amsterdam consensus, so a slower progression is common rather than a warning sign.
What if there's no athletic trainer at the school or club?
You're then looking for a clinic that runs return-to-play and return-to-learn programs directly. Across the 3,205 verified listings in our directory, 1,413 carry a Return to Play/Learn tag and 222 are sports medicine groups, though those return-to-play listings appear in 44 states rather than nationwide.
Can heart rate limits for the protocol be worked out at home?
The exercise ceiling is set by a supervised exercise tolerance test, not estimated from a fitness watch. The Buffalo Concussion Treadmill Test identifies the heart rate threshold of exercise tolerance in concussed patients, and it is run in a clinic with symptoms and heart rate tracked as the workload rises.
