The Capitals’ first practice of 2012 is underway at KCI and every player is on the ice except for Alexander Semin, who has been given a maintenance day, according to a team spokesman.

Semin played 17 minutes and 35 seconds in Washington’s 4-2 win over Columbus on Saturday, which is on par with the Russian winger’s average ice time (17:30) this year. He played eight shifts in the third period but didn’t take to the ice in the final 2:31 of regulation.

With Semin’s absence, take the line combinations the Capitals are using with a grain of salt. If Semin is able to face the Calgary Flames on Tuesday, it’s safe to assume that the configuration of the top-six forwards will be adjusted to fit him into the mix from what is being used in practice Monday.

Semin is the only player missing from the workout. Mike Green is taking part in the session and working through drills alongside John Erskine, who was a healthy scratch against Columbus.

Here are those lines and defensive pairings:
