Canadian Olympic hockey hopeful Logan Couture will have surgery Wednesday morning and miss three to four weeks, according to multiple reports.

The reports surfaced of the San Jose Sharks sniper's injury on the eve of Team Canada unveiling the squad it will send to the Sochi Winter Games next month (Watch the announcement live on Tuesday at 11 a.m. ET on CBCSports.ca).

Sharks general manager Doug Wilson said Tuesday in a statement released by the team that Couture "has been dealing and playing with an upper body injury" for the past several weeks.

"The injury has not responded as we had hoped," Wilson added. "Logan feels it is in his and the team's best interest to get the problem rectified now."

Wilson said he would have a more clear understanding of Couture's recovery time after the procedure.

Couture's Olympic status is now unclear, but Team Canada GM Steve Yzerman and his staff have the option of naming players to the squad and replacing them later if they can't suit up due to injury.

Couture, 24, is enjoying a strong season with 14 goals and 21 assists in 43 games. The six-foot-one, 200-pound winger is a former first-round pick of the Sharks (ninth overall in 2007).

The Guelph, Ont., native has 103 goals and 202 points in 275 games and signed a five-year, $30-million US contract extension with San Jose this past summer.
