The Leeds player today smashed his head with McTominay, got bandaged up, even though blood was pouring out, an he was obviously dazed, they let him carry on. Got subbed 15 minutes later couldn't even walk off the pitch. Disgusting by the physio, I think the PL need to look at this concussion subbing a little closer. He should never have carried on, was as good as dangerous to let him. They should also never ask the player if he is okay and make the decision themselves.
