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 have been blessed to play for 16 years in the NHL; it has been an amazing ride. I would like to thank the Tampa Bay Lightning and New York Rangers organizations and owners for providing me the opportunity to play the sport I love for so many years. I could have never played for so long or accomplished all that I have without the unwavering love and support from my wife, Heather, our three sons, Ryan, Lucas, and Mason, and my parents.
