Senators’ Milan Michalek has knee surgery

Ottawa Senators coach Paul MacLean says forward Milan Michalek

has undergone arthroscopic surgery on his right knee and will be

out indefinitely.

MacLean says Tuesday the surgery was to clean up debris in the

knee.

The injury caused Michalek to miss 10 games this season. He came

back for two games in early March, picking up an assist in each

game, but the knee kept bothering him.

Michalek has two points and eight assists in 15 games with the

Senators this season. He had a breakout season in 2011-12, with 35

goals and 25 assists in 77 games.

The Senators’ lineup has been depleted this year, with star

center Jason Spezza, Norris Trophy-winning defenseman Erik Karlsson

and starting goaltender Craig Anderson all out with long-term

injuries.
