Especially with it happening at the end of the game. It seems he needs to at least miss their next game.Agreed, that needs to be more than an ejection. Is that even a possibility?
F2's need to at least follow football targeting rules. If it happens in the 2nd half they should be out for the 1st half of the next game. Otherwise cheap shots like this have almost no penalty.
Add in that this is the second F2 of his season and maybe he needs to be out for a while.
