To some, February means dealing with the winter blahs. To the Edmonton Oilers, it means dealing without a starting player for the remainder of the season. 

On Tuesday, the NHL team learned Lubomir Visnovsky will undergo shoulder surgery this week and miss the rest of the season, almost one year to the day after fellow defenceman Sheldon Souray underwent season-ending arthroscopic surgery on his left shoulder.

A few days prior to Souray's operation, top centre Shawn Horcoff had season-ending surgery to repair a torn labrum in his left shoulder.

Doctors will repair the labrum in Visnovsky's right shoulder on Thursday, a team spokesman said. He suffered the injury in Edmonton's 3-1 home loss to Chicago on Feb. 3 and went on the injured reserve list two days later.

Visnovsky, 32, has eight goals and 23 points in 50 games this season, his first with the Oilers after being acquired from the Los Angeles Kings last June for forward Jarret Stoll and defenceman Matt Greene.
