Defenseman Mike Green is the only player other than Jay Beagle, who is out with a concussion, not on the ice for Capitals practice this morning.

According to team spokesman Sergey Kocharov, it’s “nothing serious,” a maintenance day for Green. The defenseman’s absence is a little curious, though, given that Washington had an off day on Sunday.

Green was hit in the chin by the puck with 2:57 remaining in the first period of Saturday’s game against Detroit. The 26-year-old Calgary native went off the ice immediately and received stitches but Green returned for the start of the second period and finished the game. He tied a career-high with four points in the contest and led the Capitals in ice time by the end of the game 22:09.

But it was a scary moment for Green, who missed time during the 2010-11 season with a concussion. After Saturday’s contest, Coach Bruce Boudreau said Green was okay.

“He got his face in the way of another one,” Boudreau said, “but it was only his jaw, so it was okay.”

Today marks the ninth consecutive practice that Beagle has missed since he was knocked out by Pittsburgh’s Arron Asham on Oct. 13.
