Nathan Horton had surgery on a shoulder injury on Wednesday, following an injury he picked up in last season's Stanley Cup final.
The Columbus Blue Jackets winger, who signed from the Boston Bruins on July 5, went into the surgery as the first step of his rehabilitation, but he is expected to miss the opening few months of next season.
Dr. Jon Warner performed the operation at the Boston Shoulder Institute at Massachusetts General Hospital.
The Blue Jackets general manager, Jarmo Kekalainen, told the team's official website: "Nathan's surgery went very well and he is expected to make a full recovery after completing his rehabilitation program.
"Since Nathan joined the Blue Jackets, our medical team from Ohio Health and team training staff have worked closely with Dr. Warner and will be actively engaged with Nathan throughout the rehabilitation process."
Horton signed on a seven-year deal worth $37.1m, and left the Bruins after winning two Division Championships, two Conference Championships and one Stanley Cup with them in 2011.
He announced at his introductory press conference that he expects to be out for four to six months.
"I've just been kind of waiting to get it done," Horton told the team's website. "I'm definitely going to have surgery. Hopefully in the next week, early week, we can figure that out and get something done, and the sooner the better. I think the recovery is four to six months. I'm hoping four, and I think everyone else would in my situation.
"I just want to be 100 percent and come back and never have a problem with it again."
