EAST RUTHERFORD, N.J. — Seven-time New York Giants Pro Bowler Michael Strahan is staying retired.

"This has been one of the toughest nights of my life," Strahan told FoxSports.com in a story released Tuesday afternoon. "But after long deliberation and throwing around a million scenarios in my head for the past day, I think it's just best if I stay retired."

Tony Agnone, Strahan's agent, did not immediately return a telephone call from The Associated Press.

Giants general manager Jerry Reese has asked the 36-year-old Strahan to reconsider his retirement on Monday, just 48 hours after the Super Bowl champions lost Pro Bowl defensive end Osi Umenyiora for the season to a knee injury in the preseason game against the New York Jets.

Strahan needed just about a day to turn down an offer to return for a 16th season with what could have been an $8 million contract.

"I really love my life now," he told FoxSports.com while on vacation in Greece. "It's great having nobody put a finger on me. You really put yourself through an awful lot in this league, more than people realize.

Reese did not seem surprised by the decision.

"We knew it was a long shot, but we owed it to ourselves to exhaust the possibility," Reese said late Tuesday evening. "We appreciate Michael even considering ending his retirement. He has a new career in front of him and we wish him nothing but the best. As we all said when he announced his retirement, Michael was and is a great Giant."

SUPER BOWL HERO DAVID TYREE: Wide receiver David Tyree was placed on the physically-unable-to-perform reserve list by the New York Giants on Tuesday, meaning the player who made a game-saving catch in the Super Bowl won't be making any for at least the first six weeks of the season.

Tyree, whose spectacular one-handed catch against his helmet sparked the Giants' late game-winning drive against the previously unbeaten New England Patriots, has not practiced since training camp opened in July because he is rehabilitating a surgically repaired right knee. He had surgery in May.

The Giants can take Tyree off the PUP list any time from the first day after the sixth week of the season until the last day of the ninth week. Once he is taken off the list, he has 21 days to either be activated or he is finished for the season.

BROWNS QB ANDERSON MAKES BRIEF APPEARANCE: Browns starting quarterback Derek Anderson made an appearance on the practice field Tuesday, his first since suffering a concussion Aug. 18 in a preseason game against the New York Giants.

He did some throwing at the beginning of practice while wearing his helmet, and left the field once team drills began.

BUCS PLACE CADILLAC ON RESERVE PUP: The Tampa Bay Buccaneers placed running back Carnell "Cadillac" Williams on the reserve physically-unable-to-perform list, meaning his bid to return from a serious knee injury will be delayed at least until after the sixth week of the regular season.
