Capitals defenseman Mike Green will undergo an abdominal surgery and is expected to miss four to six weeks, a team spokesman said Monday afternoon.

The two-time Norris Trophy finalist, who was placed on the long-term injured list last week, has played in just 10 of Washington’s 43 games this season. He missed 23 games from Nov. 12 to Jan. 3 with a strained right groin muscle and then on Jan. 7, just two games into his return, he aggravated his groin injury against San Jose. He was forced to leave that contest after playing just 7 minutes 11 seconds.

The surgery, which is scheduled for Tuesday, according to a league source, is to repair the damage from the now-chronic groin injury.

Been tough times for Green.
