They just showed a picture of him on the broadcast as he's being carried out, his eyes are open and he has his hand on his head. So apparently and thankfully, the CPR and chest shocks were able to revive him there on the field.
Watching it live, he was completely out and in dire circumstances. You could see them massaging his neck and chest area trying to get him to breath and then they moved on to chest compressions and shocks. No idea why the live feed kept showing that because that was so scary and inappropriate to show.
