Really awful injury. Can only hope it's not as severe as Ryan Mason's injury and it doesn't end his career, even if the recovery period is long. He is a great player to watch. If he is able to return, how do you rebuild the confidence to go for a header again after a collision like that? That must be a huge hurdle to get over.
And Luiz shouldn't have played on, it was ridiculous that he did. For a clash of heads, and particularly one as severe as that where you could hear it through the TV, the medics that enter the field shouldn't be club medics IMO. An impartial 3rd party medic employed by the league should be carrying out assessments and deciding if a player should continue. Not the club, and absolutely not the player. If its an important player, I believe (based on not very much at all) that a club medic will be under some pressure to give the thumbs up to the bench. Their judgement is likely to be clouded. It needs to be taken out of their hands as the first step of improving head injury protocol.
Luiz was still bleeding as the half time whistle went, I don't even think you need to be a medic to decide he shouldn't have continued. If you need to have your head taped up or stapled, you need to be off. There are no head injury heroes.
