Free agent wide receiver David Tyree knows his days in the NFL may be numbered, reports Tom Canavan of the Associated Press.

"It is very likely I could shut it down and I won't have any qualms about it," Tyree said while visiting the New York Giants' locker room on Friday. "Like I said two years ago, if everything ended with this, I'd have to be happy, amazingly happy. This has been a crazy ride."

The Livingston, New Jersey native was a sixth-round pick out of Syracuse by the Giants in 2003. In six seasons, Tyree caught just 54 passes for 650 yards and four touchdowns, making his most impact on special teams, where he totaled 68 tackles, including a team-high 16 as a rookie.

If Tyree does retire, he will most be remembered for "The Catch", a 32-yard reception on 3rd-and-5 during the Giants' game-winning touchdown drive in Super Bowl XLII. Tyree caught quarterback Eli Manning's desperation heave with safety Rodney Harrison draped all over him. Four players later, Manning his Plaxico Burress in the corner of the end zone for a touchdown.

Tyree missed the entire 2008 season with injuries, and joined the Baltimore Ravens early in the 2009 season, totaling six tackles and recovering a fumble on special teams during the 10 games he was active.
