Mitchell has not played since Game 6 of the opening round against the San Jose Sharks because of a lower-body injury. He will replace Matt Greene in the lineup.
The Kings played nearly the entire second round against the Anaheim Ducks without Mitchell and fellow veteran Robyn Regehr, who was injured in Game 1 of that series. Jeff Schultz was recalled from the American Hockey League to replace Regehr and has played well in his first NHL action of the season.
Mitchell missed all of last season with an injury, but was instrumental in the Kings' march to the Stanley Cup in 2012.
I downplayed the first one because I thought it's just a hockey game. We just want to win the game; it's against our rival and we want the two points. I downplayed it, but now having gone through the first one I look back and say, 'Geez, that was really cool.' I think as I've grown a bit older I've got a lot more appreciation for what we're allowed to do every day.
