Mitchell came to the Kings as a free agent prior the 2010-11 season. He scored a career-high five goals in 57 games a year ago while owning a plus-4 rating. He has appeared in 55 games this season, scoring three goals and owning a plus-2 rating, the only full-time defenseman in the black for the league's lowest-scoring team.
Mitchell is expected to serve as a mentor for rookie Slava Voynov, who was recalled from the AHL on Friday to replace Mitchell's previous playing partner, Jack Johnson, who was traded to the Columbus Blue Jackets on Thursday.
The Kings are scheduled to host the Chicago Blackhawks on Saturday night at Staples Center.
