Rookie outside linebacker Cameron Sheffield went down on a helmet-to-helmet hit. The Chiefs tell us it was a neck injury and he's still being evaluated.
Sheffield hit the ground after that.
Trainers came out to tend to him for 10-15 minutes before they loaded him on a stretcher and carried him out on a cart.
Just last week, the Chiefs had a similar situation with defensive back Maurice Leggett, who suffered a head/neck injury and was carted off the field. Leggett is now apparently going to be OK.
