The Kansas City Chiefs have run into another injury problem at running back.
The Chiefs announced Wednesday afternoon that running back Spencer Ware has been placed on injured reserve with what ESPN's Adam Teicher disclosed to be a shoulder injury. Defensive lineman Xavier Williams was activated to the 53-man roster from injured reserve in a corresponding move.
Kansas City signed Ware on Dec. 3 after the team sent Darrel Williams to IR with a hamstring injury. Ware played in three games and tallied 51 yards on 17 rushing attempts but did not find the end zone.
