The Kings and defenseman Matt Greene agreed Tuesday on a new four-season contract worth a reported $10.5 million. Greene, 31, was due to become an unrestricted free agent July 1, but the Kings moved quickly to keep him off the open market. It also could mean veteran defenseman Willie Mitchell, who also can become a UFA next week, does not return to the Kings.

Greene has been with the Kings since arriving in a 2008 trade with the Edmonton Oilers, helping the team win Stanley Cup championships in 2012 and ’14. The defensive-minded defenseman had six points, including two goals, in 38 games this past season. He also had four assists in 20 playoff games.
