I must be watching a different video.You can clearly see on the club extended highlights he raises and leads with his shoulder. Now we know he's not a dirty player and he probably doesn't mean it but he does catch him in the face and the player needs to go off with concussion.
Seen plenty of accidental blocks that have lead to head injuries given as reds.
Here is the point of impact - it is clearly Lamptey's shoulder that connects with Mudryk's face. Nasty injury for sure but that's not even a foul! I've never ever seen an accidental block being given as a red card. And we know that a referee's decision should not be influenced by the severity of injury.
