"Bobby has been dealing with the discomfort of this injury since it was sustained in November," Senators general manager Bryan Murray said in a statement. "Both Bobby and our medical staff were hopeful that we could hold off from having surgery until the completion of the season, but he aggravated the condition last Saturday in Dallas to the point that surgery is now the only option.
"Bobby has worked hard to play through this injury to help his team and his teammates, and had yet to miss a game this season prior to the injury progressing to this point, so we're obviously disappointed that we won't have him available to us for the rest of the season. We're confident that he'll recover in time to have a full summer of training that will allow him to be back in our lineup and help this team be successful next season."
Ryan, acquired from the Anaheim Ducks in July 2013, leads the Senators with 23 goals.
