I read in the paper today that Gallen has apologised for all the garbage in his game, and he's asked for forgiveness, stating that he's a win-at-all-costs kind of player, which IMHO is what the Sharks need.
In the article, which
you can read here, from todays Daily Telegraph (it's all there is to read at work), Gallen said that he was trying to rip the tape off - but as you can see from the pic, he can't actually see Laffranchi's head, so he's just aimlessly ripping. His thinking was to show the ref that Laffranchi shouldn't have been back on, and to try to gain an advantage for his team.
As a sharks fan, I've heard the promises from him before, so I hope that a suspension will actually make him think more about his on-field actions.
