It is a Friday night in October, the field lights are on, and a sophomore goes down awkwardly after a tackle. Within seconds someone in a windbreaker is jogging out from the bench. If you are in the stands, you probably cannot tell whether that person is the trainer, the coach, or a doctor, and you certainly cannot tell what they are deciding.
Most people picture the team physician role as watching a game with a better view. It is closer to running a small, mobile clinic in uncertain conditions, with a crowd, a clock, and a teenager who very much wants to go back in. Here is what the job actually involves, and why it tends to change how a physician practices afterward.
The work starts long before anyone kicks off
By the time the whistle blows, most of the preparation is already done. Before a season starts, the medical staff is generally involved in:
- Preparticipation evaluations, which exist to find the small number of athletes for whom playing carries real risk, and to flag the asthma, old injuries and heart history that would otherwise surface at the worst moment
- The emergency action plan, meaning a written, rehearsed answer to questions like who calls 911, where the ambulance enters, who meets it, and where the nearest AED is kept
- Environmental planning, including heat and hydration policies, lightning protocols, and in Colorado, altitude considerations for visiting teams
- Equipment and facility checks, from helmet fit to whether the field has a hole in it
None of this is visible on game night. All of it is why game night usually goes fine.
On the sideline, the job is triage, not diagnosis
A sideline is a bad place to make a precise diagnosis. The light is poor, there is no imaging, the athlete is full of adrenaline, and there are roughly ninety seconds of attention available. So the sideline evaluation is built around a narrower set of questions.
The first is whether this is an emergency. Head and neck injuries, breathing problems, chest pain, suspected fractures with deformity, heat illness and anything involving loss of consciousness are handled on a different track entirely, and the answer is transport, not a taping job.
The second is whether this athlete can safely continue. That is not the same as whether they want to, and it is not the same as whether the injury is serious. A mild ankle sprain may be minor and still make an athlete unable to protect themselves on the next play.
The third is what needs to happen in the next 24 hours: ice and elevation and a clinic visit Monday, or an X-ray tonight, or a call to a parent who is not at the game.
Why concussion gets its own set of rules
Of everything that happens on a sideline, head injury is the area where the decision is most constrained, and deliberately so. Current practice across youth and school sports generally holds that an athlete with suspected concussion is removed from play and does not return that day, even if symptoms seem to clear within minutes.
That rule exists because the sideline cannot reliably rule a concussion out. Symptoms can be delayed, athletes underreport, and the consequences of a second impact before recovery are the ones nobody wants to explain to a family. In Colorado, youth concussion removal and return requirements are set in state law, which means this is not a judgment call a coach gets to override.
If you are a parent trying to understand what to watch for after a hit, our guide to concussion signs every Colorado parent should know covers the symptoms that matter and the ones that mean go now.
What “cleared” actually means
Return to play is rarely a single moment. For most injuries it is a graded progression: rest or relative rest, then light activity, then sport-specific work, then contact or full participation, with each step held long enough to see whether symptoms return.
The physician’s part is mostly judging two things. Has the tissue actually healed enough to tolerate the demand, and can this athlete perform the specific movements their sport requires without compensating in a way that will create the next injury? A goalkeeper and a distance runner with the same shoulder problem are not the same decision.
Done well, this is slower than athletes want and faster than anxious parents expect, which is usually a sign it is calibrated about right.
The parts nobody mentions
A sideline physician also spends a surprising amount of time on things that are not injuries. Talking a nervous freshman through an asthma flare. Noticing that an athlete has lost weight over a season. Catching a skin infection in a wrestling room before it spreads. Having the conversation with a senior whose knee is not going to be ready for the game that matters to them.
There is also a quieter responsibility, which is holding the line when the pressure runs the other way. Coaches, parents and athletes all have reasons to want someone back in the game. The medical decision has to sit outside that, and the role only works if everyone understands in advance that it will.
Why any of this matters if you are not an athlete
Sideline work builds a particular skill set: evaluating a musculoskeletal problem quickly and with your hands, deciding what is urgent without reflexively ordering a scan, and thinking in terms of returning to an activity rather than just reducing a symptom. That translates directly to a 48-year-old whose shoulder hurts when they reach overhead.
Dr. Kroner has been a family practice and sports medicine physician since 2013. His sideline and team experience includes serving as a team physician for the Anaheim Ducks, USA Water Polo and two university athletic programs, as medical director for the West Coast for RunDisney, and as a high school sideline physician for fifteen years. You can read more on the meet the doctor page.
In practice that means the same evaluation that happens on a field happens in the office, with more time and better light. If you are curious what that specialty actually covers, we wrote about what primary care sports medicine is and who it tends to help.
If your athlete needs a physical or an injury looked at
Ridgeview offers preparticipation sports physicals as well as evaluation of in-season injuries. Sports medicine visits are included for members, and standalone visits are open to anyone, including families whose primary care is elsewhere. A direct primary care membership is not health insurance; it covers the care you receive with us, and you should still carry coverage for hospitalization, imaging and specialty care.
If an injury just happened and your athlete has a deformed limb, cannot bear weight, has neck pain, is confused or lost consciousness, do not wait for an office appointment. Head to urgent care or the emergency department.
Book a free 30-minute meet and greet with Dr. Kroner on our contact page, or call 720-807-9961. Ridgeview Direct Care is at 4045 Wadsworth Blvd #300, Wheat Ridge, CO 80033, open Monday through Friday, serving Arvada, Lakewood, Golden, Edgewater and west Denver.
