Vince Wilfork wants release

New England Patriots defensive tackle Vince Wilfork has asked the team to release him after 10 seasons, according to sources.

NFL Network, citing sources, first reported Wilfork was seeking his release.

Wilfork is in the final year of his contract and was scheduled to earn a base salary of $7.5 million and count $11.6 million against the salary cap. Sources previously told ESPNBoston.com that the Patriots recently approached Wilfork about altering his contract.

Wilfork, a team captain who joined the Patriots as a first-round draft choice in 2004, was limited to four games last season because of a torn Achilles.

The 32-year-old is a five-time Pro Bowler and has been one of the NFL's premier run-stuffers, displaying uncommon athleticism for a player his size (6-foot-2, 325 pounds).

He's also been a fixture in the area, earning the team's community service award in 2010.
