Detroit Lions lose best defender to injury after he tackles quarterback

The Detroit Lions have had more than their share of injuries so far this season and it looks like that trend has continued as their best defensive player (in my opinion) has gone to the medical tent to be checked for a concussion.

Walker was hurt when he put a big hit on Pittsburgh Steelers QB Mason Rudolph as he scrambled for a first down.



Walker is headed to the Detroit Lions locker room. Chances are that he is done for the day.
