Apparently the guys who know the rules said it didn't violate rule 48.

I didn't really see anything wrong with the hit myself. Anyone who knows hockey knows you don't skate behind the net with your head turned because you're going to get hit. Torres didn't leave his feet, didn't use his elbow or forearm, and didn't charge. He turned so that he didn't knock Seabrook into the boards, and he put his shoulder at Seabrook's shoulder. Seabrook turned at the last second and got caught in the chest with most of the hit, and got some in the head too, but that wasn't Torres' fault.
Seabrook was very close to touching the puck so it was interference only by a fraction of a second. If Torres had touched the puck himself, he'd be in the clear.
