You don't want to lose any playing time—and I'm guilty of this for a shoulder injury—because you're doing something you enjoy. Or maybe it's the playoffs and you don't want to lose the opportunity for that and let your team down.
Knowing all of these reasons is really helpful and important, because then we can start addressing them. If, for example, a student athlete is worried that their coach is going to be upset, then we can address that with education, perhaps where both of them are sitting at the same table, making sure there's a common understanding and expectation for the reporting of concussions.
