EL SEGUNDO (AP) — The Los Angeles Kings have placed Mike Richards on injured reserve after the star center sustained a hit to the head.

The Kings also activated left wing Dustin Penner from injured reserve on Friday.

Coach Terry Murray said Richards will be out for at least a few games after getting hurt late in the second period of Los Angeles’ 2-1 win over Florida on Thursday night in a collision with Sean Bergenheim. The NHL won’t pursue supplemental discipline against Bergenheim.

Richards is the Kings’ second-leading scorer with 20 points in his first season with Los Angeles.

Los Angeles didn’t place Willie Mitchell on injured reserve Friday, but Murray expects the defenseman to miss several games with a lower-body injury after playing just one first-period shift against the Panthers.
