The tip of Nosal's pinky finger was severed and went missing during the CMU game when it got caught up in a face mask. The prudent course of action, have the rest of the finger wrapped and continue playing of course. The piece was later found in Nosal's glove, and was sewn on after the game.
To summarize, on Saturday afternoons Greg Nosal's agenda is to plow the field with the ass of anyone who crosses his face. he'll continue doing so with or without the cooperation of his appendages.
