The future of the Raiders took a big hit that could force a step back on Friday night. Rookie quarterback Derek Carr suffered a concussion and bruised (or worse?) ribs after getting turned into the deli meat of a Larry Webster-and-turf sandwich.
With just 5:40 to play in the game, the Lions defensive end blew past backup tackle Jack Cornell, walked down Carr from his blindside and smothered him into the ground.

So big brother never taught Derek how to take a sack? After all of David's experience with it?

Looks like it will be Schaub on Opening Week for the Fade.
