is week-to-week with an upper-body injury, the Kings announced Thursday.
Clifford was knocked out of Wednesday’s game on a hit by Calgary Flames defenseman Michael Stone. The injury is a blow to an effective Kings fourth line of Clifford, Nick Shore and Trevor Lewis. They combined for two goals and two assists and carried a plus-four rating through the first two games.
A recall was not immediately expected. The Kings have Jonny Brodzinski and Nic Dowd as extra forwards.
