ORCHARD PARK, N.Y. (AP) - The Buffalo Bills have signed center Eric Wood to a contract extension.
The new deal is for four years, a person familiar with the negotiations told The Associated Press. The person spoke on the condition of anonymity because the Bills did not announce the terms of the pact Friday.
Wood, 27, is Buffalo's best offensive lineman and is one of the team's most valued leaders. Selected 28th overall in 2009, Wood has started all 47 games played with the Bills.
It was vital that the Bills lock up their top offensive lineman after one of Wood's former teammates, guard Andy Levitre, left in free agency. Levitre signed a six-year, $46.8 million contract with Tennessee in March.
Also Friday, quarterback Matt Leinart was released.
Leinart, 30, joined the Bills on Sunday as an injury replacement. The former first-round pick struggled in his only game with the Bills on Thursday night against Detroit, completing 3 of 10 passes for 11 yards and two interceptions.
The move was the latest setback for Leinart, a former Heisman Trophy winner. Leinart has been unable to establish himself in the NFL following a standout college career at Southern California. He has had stints with four different teams over the past eight years.
NOTES: Also released on Friday were DE Kourtnei Brown; RB Zach Brown; DB Crezdon Butler; G Antoine Caldwell; G Zack Chibane; DB Jordan Dangerfield; TE Dorin Dickerson; DB Kip Edwards; RB Kendall Gaskins; DT Jarron Gilbert; DB T.J. Heath; WR Brandon Kaufman; LB Keith Pough; TE Nick Provo; T Zebrie Sanders; LB Brian Smith; C David Snow. ... The Bills finished the preseason 2-2.
