The Kings activated left wing Kyle Clifford from injured reserve before Saturday’s home game against the Colorado Avalanche. They placed forward Trevor Lewis on IR. Clifford was sidelined by a concussion since he was injured during the Kings’ victory Nov. 9 over the Vancouver Canucks. Lewis has an unspecified lower-body injury. Clifford had one goal in 16 games. Lewis was scoreless in 23 games. Forward Jeff Carter (broken foot), defenseman Matt Greene (upper body) and goalie Jonathan Quick (groin strain) remain on the IR.
