Philadelphia Flyers captain Chris Pronger will undergo surgery Tuesday to clean out loose particles in his left knee and the team expects he will be back playing in four weeks.
The veteran defenseman hasn't played since November 19, missing the last four games because of an illness.
"We were hopeful that the time missed with a virus that Chris has been fighting would settle things down in his knee but after an examination yesterday, it was decided that the surgery is the way to go at this time," Flyers general manager Paul Holmgren said in a statement on Monday.
Pronger also missed six games earlier this season after being hit in the right eye with a stick. He has one goal and 11 assists in 13 games this season, his third with the Flyers.
His surgery on Tuesday afternoon will be performed by Dr. Peter DeLuca, who is the head physician for the Philadelphia Eagles and a consultant for the Flyers.
