Well, it wasn't quite as spectacular as Steve Downie's hit on Dean McAmmond last season (nor was it as illegal), but Tomas Kopecky laid one heck of hit down on Montreal Canadiens prospect Matt Carle (not Tampa's Matt Carle).
The video only shows the hit once, but I'm sure it's clean. Actually, it looks a lot like the hit Jordin Tootoo laid on Daniel Winnik last season, although with a clean shoulder instead of a nasty elbow, but similar in terms of a blindsiding aspect.
I don't think it'll have to be reviewed, but I sure feel sorry for Carle. Getting knocked out is never fun.
