Weight, 39, who suffered the injury in November, said the pain was impacting his performance and inhibiting his ability to contribute.
"It's not the type of hockey I wanted to play," Weight said yesterday before the Islanders hosted the Devils. "I couldn't finish a check, I couldn't take a check, I couldn't handle the puck, I couldn't shoot the puck with the velocity I was used to. I was spending 80 percent of my shift positioning myself so I didn't blow my shoulder out."
Weight, who had one goal and 16 assists in 36 games, said he's eager to finally resolve the issue.
"I'm relieved I'm doing it," Weight said. "I don't want to feel this anymore. It's going to be a tough process, but I'm ready to tackle it."
Weight said the surgery, which will be performed at the Cleveland Clinic on Thursday, was always going to be necessary but added that he wanted to make an attempt to lead the team to the postseason.
Weight has scored 1,024 points in 1,220 games since coming into the league with the Rangers in 1991 and playing for six different teams. He said that if Thursday's game against St. Louis was his last in the NHL, he has no regrets, but that he will attempt to return.
"It's pretty invasive surgery and I'm going to approach it with the aspirations of still playing hockey," Weight said. "I've still got the fire in my stomach when I hit the ice. My legs still feel strong. I feel strong on the puck . . . I'll approach it to come back with 100 percent aggression. I don't know if that will be with the Islanders or not. We'll cross that bridge when we come to it."
Weight said he's looking forward to the mental and physical relief the surgery and subsequent rest will bring.
"I'm not trying to say it was heroic by any stretch of the imagination, but it was frustrating," he said.
Islanders coach Scott Gordon said Weight's toughness was an example to all.
"If it were any other player, he would've gotten surgery in January," Gordon said. "He gave it his best shot."
Teammate Matt Moulson said it was difficult for everyone to see the pain Weight endured daily. "Even putting on the jersey was tough for him," Moulson said. "To see a guy like that, his love for the team and game, it's tough. We'll definitely miss him."
