Tie Domi played almost the entire season with a debilitating hip condition and will undergo surgery next week to repair the damage.

The Leafs winger revealed his ailment yesterday — along with a broken left hand and damage to his vocal chords — as the Leafs lifted the veil of secrecy on a host of injuries to key players.

``To be honest with you, I played pretty much the whole season with it. ... I took a lot of treatments," Domi said as the Leafs cleaned out their lockers.

Mats Sundin and Joe Nieuwendyk also revealed they were both suffering from damaged groin muscles that had torn off their respective pelvic bones.

Speculation — due to the team's traditional post-season secrecy — had Sundin suffering from a variety of injuries. It was believed he originally injured his ankle, then his knee, and finally, tore muscles in his quadriceps.

Nieuwendyk was similarly misdiagnosed. He was believed to be suffering from recurring back spasms, but he said that problem corrected itself in the first round against Ottawa.

"I missed that game against Ottawa and that was the only episode I had with the back," said Nieuwendyk, who is part of a group of four veterans — Gary Roberts, Eddie Belfour, and Ken Klee — the Leafs will likely return for next season.

"The three games (he missed) against Philadelphia wasn't my back. I had a groin muscle tear. So you can diffuse those back rumours right now."

Sundin said the groin muscle injury that forced him out of two playoff games was compounded by several events in a game against Ottawa. He was originally thought to have suffered the injury when he was pulled down by Wade Redden on a partial breakaway.

"I felt a bit of a pull in the second period against Ottawa, then I tore it right off the bone on that play (breakaway)," Sundin said.

"It wasn't when I slid into the boards. The doctors said they haven't seen something like that almost ever."

Domi, meanwhile, nursed himself through an athritic condition on his hip, a condition that saw Alex Mogilny undergo surgery in Pittsburgh in early January and miss 20 games.

"It was a tough injury to play with, the same thing Alex had, and he had surgery," said Domi, who was among the Leafs' most consistent performers in the playoffs.

"It was his choice. I felt if I had the surgery it would have been hard for me to play the whole season."

Domi plans a trip to Pittsburgh early next week and will have the operation performed by the same doctor who worked on Mogilny, Dr. Alex Phillipson.

Domi said he'll need between six and eight weeks of rehab after surgery.

Domi also said he broke a bone in his left hand during a fight with Chris Neil in Game 4 of the Ottawa series.

He also took a puck in the throat in February and lost his voice for almost a week.
