ATLANTA -- The Atlanta Falcons found a replacement for John Abraham on Wednesday by reaching an agreement with free-agent defensive end Osi Umenyiora on a two-year, $8.5 million contract.
The Falcons released the 34-year-old Abraham, the team leader with 10 sacks in 2012, on March 1, the same day they also released running back Michael Turner and cornerback Dunta Robinson.
The team replaced Turner by signing Steven Jackson to a three-year, $12 million deal March 14. Now Umenyiora joins Jackson as Atlanta's second major free-agent addition.
The Falcons scheduled a news conference with Umenyiora for Thursday (see full story).
Browns sign Jason Campbell
The Cleveland Browns have signed free agent quarterback Jason Campbell to a two-year contract, bringing the veteran in to provide competition for Brandon Weeden.
Campbell, a first-round pick by Washington in 2005, has started 77 games and thrown 76 touchdowns during his NFL career. He played his first five seasons with the Redskins before he was traded to Oakland in 2010. Campbell spent two seasons with the Raiders.
He went 4-2 in his first six games as Oakland's starter in 2011 before sustaining a broken collarbone that ended his season. He signed with Chicago as an unrestricted free agent in 2012 and made one start.
The Browns have been looking for a QB to bring in and push Weeden, who had an uneven rookie season. Campbell could challenge Weeden for the starting job.
Ravens ink Huff to replace Reed
The Baltimore Ravens have agreed to a three-year deal with former Oakland Raiders safety Michael Huff.
Huff played his entire seven-year with the Raiders before being released last week. The 29-year-old visited the Dallas Cowboys earlier this week.
He must pass a physical before he can sign a contract.
The Ravens announced the agreement Wednesday. Huff is expected to fill a void in the backfield for the Super Bowl champions, who previously this offseason released starting strong safety Bernard Pollard and lost free safety Ed Reed to Houston via free agency.
Huff started all 16 games for Oakland last season -- 14 at cornerback and two at free safety. He had 71 tackles and two interceptions.
The 6-foot, 210-pound Huff has 11 career interceptions and 453 tackles in 108 games.
Chargers part ways with OT Gaither
The San Diego Chargers have released left tackle Jared Gaither, which will cost them a $6 million hit against the salary cap.
Gaither was signed to a four-year, $24.5 million contract after playing well in the final five games of 2011. But he developed a mysterious back injury early in training camp last summer and was slow to return, raising questions about his work ethic. He played in only four of the first 10 games before injuring his groin and going on injured reserve.
The Chargers are expected to take an offensive lineman in the draft next month.
Greg Jones signs with Texans
The Houston Texans have signed unrestricted free agent fullback Greg Jones.
The 6-foot-1 Jones is the third free agent to sign with Houston since Friday, joining safety Ed Reed and punter Shane Lechler. Terms of Jones' contract were not disclosed.
The Texans needed a fullback after James Casey signed with Philadelphia after free agency opened.
Jones has played his first nine NFL seasons with Jacksonville. The Jaguars drafted him in the second round in 2004. Jones helped Jacksonville running backs rush for 100 yards in a game 37 times.
Jones ran for a career-high 575 yards and four touchdowns in 2005. He missed the 2006 season with a torn left anterior cruciate ligament, then played in all 16 games in 2007.
Cowboys sign two on defense
The Dallas Cowboys have signed safety Will Allen and linebacker Justin Durant to free-agent contracts.
Dallas was able to sign the two defensive players Wednesday after restructuring the contract of backup quarterback Kyle Orton and releasing receiver Anthony Armstrong to clear enough salary-cap space. Allen and Durant could be potential starters in the Cowboys' new 4-3 scheme with new defensive coordinator Monte Kiffin.
Durant started 14 games and had 103 tackles last season for Detroit, where he played the last two years after starting his career with four seasons in Jacksonville.
Allen spent the last three seasons in Pittsburgh after six in Tampa Bay. He has started 33 of his 130 NFL games with 238 tackles, four interceptions and 11 pass breakups.
