Kings defenseman Alec Martinez had finger surgery Friday.

If it’s not one thing, it’s another for the Kings. Just when it seemed their defense crops might be back to something close to full strength again, they lost another valuable member when Alec Martinez underwent finger surgery Friday morning.

Kings general manager Dean Lombardi informed the club’s website of Martinez’s surgery, but did not provide further details. It wasn’t immediately certain how long the Stanley Cup playoffs hero would be sidelined, or precisely what was done during the procedure.

Martinez, who scored the series-winning goals in Game 7 of the Western Conference final against the Chicago Blackhawks and Game 5 of the Stanley Cup Final against the New York Rangers, was injured while blocking a shot in the second period of Thursday’s loss to the Dallas Stars.

His absence means the Kings are down to only six healthy and eligible defenseman again, with Robyn Regehr poised to return to the lineup for today’s game against the Ducks after sitting out three contests because of a lower-body injury.

Slava Voynov continues to serve an indefinite suspension imposed by the NHL after his arrest last month on domestic violence charges after an incident at his Redondo Beach home. The Kings placed him on non-roster status earlier in the week in order to sign free agent Jamie McBain.
