He has broken his nose and upper jaw - and a concussion. There might be the possibility to play with a mask - but there will be further check-ups before to see how risky this is. That is why there is no official statement right now how long he will be out.
So apparently the latest news coming out is saying that he did not break his nose, nor did he have a concussion. The only thing broken are his jaws.
How does that mask he is wearing shown in the picture above is going to protect his jaws, as they are left completely exposed? Is he wearing it to intimate our players?
