Forward Paul Gaustad will undergo season-ending shoulder surgery, generam manager David Poile confirmed on Thursday. The recovery time for the surgery is four-to-six months. Gaustad is doing it now in hopes of being ready for the 2013-14 season or training camp. The 6-foot-5, 223-pound Gaustad has been hurt off-and-on this year with the issue, and played in 23 games. He also missed six games with an unrelated “upper body” issue. The Predators acquired Gaustad last season in a package that included Nashville's 2012 first round draft pick. Gaustad is one of the top face off men in the NHL, posting a 59.7 percent rate in the circle.

Poile also said forward Colin Wilson will miss the remainder of the regular season with the same shoulder procedure as Gaustad. Wilson was the Predators' leading scorer at the time of his injury on March 9 with 19 points in 25 games.
