They have independent nero doctors who are responsible for concussions.
Everyone keeps saying this, and it makes zero sense. The teams should still hold some responsibility when in comes to head injuries. The guy was squinting, sniffing smelling salts minutes in to the game, and ended up putting on a tinted visor because of light sensitivity. Someone on the team should have caught this and there are no ifs ands or buts about it. I don't give a shit about the independent doctors and spotters. Just because those people exist doesn't mean common sense is thrown out the window.
