The Buffalo Bills ended Darwin Walker's holdout by trading the disgruntled veteran defensive tackle to Chicago. In exchange, the Bills received an undisclosed pick in next year's draft. The deal marks the second time the seven-year veteran has been traded since March, when Buffalo acquired him in a deal that sent linebacker Takeo Spikes to Philadelphia. Walker, however, had refused to report to Buffalo until the team renegotiated the remaining two years on his contract. He was scheduled to make $1.3 million this year and $1.4 next season.

Running back Marshawn Lynch, the Bills' first-round draft pick, agreed to a five-year contract worth nearly $19 million Thursday night, the player's agent told The Associated Press. "Marshawn's ecstatic and looking forward to helping the Bills," Doug Hendrickson said. "All along, Marshawn told us he wanted to be in camp on time and instructed us to get the deal done." Drafted 12th overall out of California, Lynch will earn $10.285 million in guaranteed money including bonuses, with the entire contract worth $18.935 million.

Linebacker Paul Posluszny signed a four-year deal with Buffalo potentially worth over $5 million on Wednesday, a day before the start of Bills training camp. The two-time All-American agreed to a deal that includes $2.55 million in guaranteed money and is worth $4.75 million overall. It also includes $325,000 in incentive clauses.

The Bills signed quarterback Trent Edwards, the team's third-round draft pick, on Tuesday. Edwards, drafted 92nd overall out of Stanford, is the second of the team's seven draft picks to sign. The Bills inked seventh-round selection C.J. Ah You, a defensive end, last month.

Pro Bowl punter Brian Moorman plans to finish his career with the Buffalo Bills after signing a three-year contract extension on Monday. The contract locks Moorman in through 2012, and is worth $10 million, putting him among the league's best paid punters. As part of the deal, the Bills also restructured the remaining three years on his current contract. "It means a lot to me to have them say, 'Hey, we want you to finish you career here,"' Moorman said. "I can't say enough about how excited I am."
