called for? What rule does it break? It doesn't break any rule I've ever heard of in football. Not to mention it's a WR screen completed pass on the DE's side and the block is not traditional pass protection its blocking for the WR on the WR screen. The play is very much still live and ongoing (most importantly you block until you hear the whistle). Takes the DE out of any pursuit. The DE was that players assignment in blocking for the WR not for the QB in pass protection. Nothing illegal about a block like that so long as you don't lead with your head. No rule that it breaks. Even if it weren't a screen play, nothing illegal at all about blocking until the whistle blows.
