I didn't watch the play in detail, just saw a quick highlight. The Bears didn't seem to complain after the game about it, so it must not have been an obvious penalty. But they do have some dumb rules for trying to block kicks...no hitting the long snapper, only being able to jump straight up without getting a running start and no climbing on the back of a lineman. Vikings made a living back in the day blocking kicks by jumping on someone's back!!
