In the world of team sports, it is commonly understood and acknowledged that the onus of caution is on the organizations and not the individual players. You see these a lot more in football and soccer, where head injuries happen with a higher frequency, but not only with those, but any type of injury, players will always want to be out there.
It is not unheard of, but rare is the occasion when a player removes himself from a situation because he feels something isn’t right. That just does not happen, nor should we expect that out of them.
