ORCHARD PARK, N.Y. (AP) - Buffalo Bills general manager Buddy Nix hasn't ruled out the possibility of re-signing guard Andy Levitre, or determined whether to keep quarterback Ryan Fitzpatrick.

Nix says the team is ``still in the process of working on it,'' when asked about both players Tuesday.

Time is running out for Buffalo on Levitre, a four-year starter who is eligible to become a free agent March 12.

Fitzpatrick's future remains in question. He's coming off his second inconsistent season as starter. He's also due to earn a $3 million bonus this month as part of a six-year, $59 million contract extension he signed in October 2011.

Saying he's spoken with Fitzpatrick several times this offseason, Nix declined to reveal whether he's discussed having the quarterback restructure his contract.
