According to reports out of Montreal, when Laine left the game, he did so on crutches. Today, the NHL star is going to be evaluated so that they can fully diagnosis whatever it is he may have wrong with him. That said, the fact that he was on crutches is certainly going to make a lot of fans uneasy.
Hopefully, the injury is not serious and Laine can come back sooner rather than later. You never like to see guys go down in this fashion. Even when accidental, knee-on-knee hits are dirty and you need to do better when positioning yourself on the ice.
