The Buffalo Bills have claimed Dowtin off waivers from the Philadelphia Eagles.
Dowtin entered the NFL with the New York Jets last season as an undrafted free agent out of North Alabama. He appeared in three games for the Jets after being elevated from the practice squad on Oct. 17.

Dickerson has accepted the Bills' tendered contract offer.
Dickerson was used as a pass-catching halfback in former coach Chan Gailey's system last year. The second-year player had nine catches for 117 yards in 2012 after signing with the Bills in May.

The Buffalo Bills have re-signed Choice.
Choice, who was a free agent, enters his sixth NFL season. Buffalo claimed him off waivers in late November 2011. He had 47 carries for 193 yards and a touchdown in 12 games last season playing behind starters C.J. Spiller and Fred Jackson.

Kolb has arrived in Buffalo to officially sign his two-year contract with the Bills. The Bills announced the signing Monday, a little over a week after the free agent agreed to a two-year contract potentially worth more than $12 million.
The sixth-year player spent the past two seasons in Arizona, where injuries hampered his opportunity to prove himself as a starter. He was cut by the Cardinals last month in a salary-cap saving move. In Buffalo, he gets the opportunity to compete for the starting job with Tarvaris Jackson. The Bills are in need of a starter after Ryan Fitzpatrick was released last month.

The Cardinals have released Kolb, ending the quarterback's two injury-filled seasons with the team.
The team's move on Friday came just ahead of the deadline for paying Kolb a $2 million roster bonus. The team paid Kolb some $20 million over two seasons after acquiring him in a trade that sent a second-round draft pick and cornerback Dominique Rodgers-Cromartie to the Philadelphia Eagles.

The Buffalo Bills began addressing their needs at linebacker by signing free-agent Manny Lawson to a four-year contract. The Bills announced the move Wednesday, a day after the NFL's free agency period opened. A person familiar with the contract provided the length of the deal, and spoke on the condition of anonymity because the Bills did not reveal the terms.
Listed at 6-foot-5 and 240 pounds, Lawson played the past two seasons with the Cincinnati Bengals. He spent his first five seasons with San Francisco, after the 49ers selected him in the first round in the draft. Lawson had 47 tackles and two sacks in 16 games, including 10 starts, last season. Overall, he has 18 sacks, two interceptions and seven forced fumbles in starting 81 of 96 career games.

A person familiar with the negotiations says the Buffalo Bills have reached an agreement to re-sign McKelvin to a four-year contract worth a little over $20 million.
McKelvin is Buffalo's 2008 first-round draft pick, who was eligible to become a free agent on Tuesday. He was used mostly as a third cornerback last year, when he finished with one interception in 13 games, including four starts. Overall, he has six interceptions in 64 career games, with only 33 starts. McKelvin has made a bigger impact on special teams having scored four touchdowns returning kickoffs and punts, including two last year.

Caussin remains under contract with the Bills for next season.
The Bills said Thursday they've retained Caussin by rolling over the final year of his contract. He missed last season while recovering from right knee surgery. Buffalo acquired Caussin in December 2010 by signing him off Jacksonville's practice squad. He has five catches for 41 yards in six games with Buffalo.

Linebacker Bryan Scott says he's signed a one-year contract to remain with the Buffalo Bills, and forego the chance to become an unrestricted free agent next week. Scott first announced the signing on his Twitter account Wednesday. He confirmed it to The Associated Press by phone from his offseason home in Atlanta.
Scott is a 10-year veteran, who has spent the past six seasons in Buffalo, where he's filled various roles. Scott has played linebacker and safety and been a regular on special teams.
