The Bruins acquired Manny Fernandez in July.
Manny Fernandez will likely miss the remainder of the 2007-08 season after undergoing knee surgery Wednesday morning.
The surgery repaired a chronic tear of Fernandez's medial collateral ligament in goalie’s left knee.
"It's been a chronic thing all year," GM Peter Chiarelli told the Boston Globe, "Manny felt he couldn't perform at 100 percent. He had to alter his style. We felt that it would be best to do it now. Likely that he'll be gone the whole year - maybe not - but he'll be ready for next year at the latest."
Fernandez has not played since Oct. 22. Originally out of the lineup because of back spasms, on Oct. 30, he strained his left knee in practice.
It's the same knee he injured last January, ending his season with the Minnesota Wild.
Boston traded forward Petr Kalus and a fourth-round draft pick to Minnesota for Fernandez in July.
Fernandez had a 2-2 record and a 3.93 goals-against average in four games.
Alex Auld is 3-0 since being acquired from Phoenix last week after starting goalie Tim Thomas was hurt, but Thomas is expected to return soon.
