"It is a simple debridement," said Ronnie Barnes, the team's Vice President of Medical Services. The procedure was performed by team physician Dr. Russell Warren at the Hospital for Special Surgery in Manhattan.

Umenyiora's knee has bothered him for some time. He did not practice during the first two weeks of training camp. Umenyiora returned to the field on Monday and participated in three practices.

"Osi called me at the end of the day yesterday to let me know that he wanted to have the surgery now," General Manager Jerry Reese said. "After practicing for three days he had some swelling in the knee, and it was clear that we were going to have to adjust his practice routine to every other day to maintain his knee. Osi's feeling is he wants to get it cleaned up now because he is looking forward to playing this season, and he wants to (play) without the knee being an issue for him. He told me how much he really enjoyed being back on the field this week, and he's looking forward to getting back out there once he recovers from the procedure."

"It was better to do it now as opposed to mid-season," said Umenyiora, the Giants' two-time Pro Bowler. "It was going to have to be done, the only question was when. If I'm going to miss a little while, I would prefer it be now than at the crucial part of our season. It's the best decision for the team and myself."
