Doughty was probably in the corner cross checking him and telling him his dad was a ***** or something seconds before this happened. Let the boy stand up for himself! The NHL has a 2 minute elbowing penalty for a reason. The refs were negligent (nothing new) and missed handing it out in game, I don't think there's any need for further suspension. If tkachuk doesn't make that elbow, doughty pounds him into the end boards from behind. His elbow was higher than it should have been, but the intent of the play was to pop back, both to protect himself and cause separation. No intent to injure, no injury, just hard hockey. Doughty deserved it.
