Kansas City tight end Kevin Boss has taken a shot to the head following a second-quarter catch and will not return to Sunday's game against the Buffalo Bills.
After catching a 29-yard pass from Matt Cassel, Boss was falling down when Buffalo's Da'Norris Searcy's forearm hit the back of Boss' head. The receiver's head then hit the ground hard.
Boss stayed down for a few minutes before walking off the field under his own power. He sat on the bench for a few minutes, and was then escorted off the field.
Bills safety George Wilson also left after receiving a blow to the head when trying to tackle Boss two plays earlier. He returned in the second half.
