The Browns have acquired Lewis from the Philadelphia Eagles in a trade for linebacker Emmanuel Acho.
Lewis played 24 games in two seasons with the Eagles, who selected him in the fifth round in 2011. He rushed for 171 yards on 36 carries and scored two touchdowns. The 5-foot-8, 195-pound Lewis also returned kickoffs for Philadelphia as a rookie and will likely be a candidate to take over those duties for Cleveland. Lewis averaged 21.6 yards on 31 kickoff returns in 2011.

The Browns signed Nelson to a one-year contract Monday.
Nelson, who played three seasons for Buffalo, is coming off a torn anterior cruciate ligament suffered in last season's opener. The 6-foot-5, 214-pounder started 17 games for the Bills, who signed him as an undrafted free agent in 2010. Nelson had 94 catches for 1,042 yards and eight touchdowns with the Bills. In 2011, he was second on the club in catches (61) and receiving yards (658). He also had five TDs.

The Browns signed Campbell to a two-year contract on Tuesday, bringing him to provide competition for fellow quarterback Brandon Weeden.
A first round pick by the Redskins in 2005, Campbell has started 77 games and thrown 76 touchdown passes in eight seasons. Weeden's starting spot might not be completely assured after an up-and-down rookie season.

The Cleveland Browns signed Barnes to a one-year contract. Barnes has played in 31 career NFL games for Washington and Detroit.
He was drafted by the Redskins in the third round in 2009 and played in 15 games. In 2011, he recorded a career-high 26 tackles and two interceptions in 15 games. He was traded to the Lions last year and played in two games before he was waived on Sept. 18.

Richardson has been sued by two women who say they were assaulted at his home last year. A lawyer for Krystal Jones of Maple Heights and Kathleen Hunter of Cleveland says the lawsuit was filed Friday in Cuyahoga County Common Pleas Court. A Browns spokesman declined to comment. Richardson's agent didn't immediately comment.
The complaint, obtained by the Plain Dealer of Cleveland, says the women were invited to Richardson's Columbia Station house in December but soon asked to leave. It says Richardson then cursed the women for "slamming a door" and "disrespecting his house." The lawsuit says Richardson banged on Jones' vehicle, causing damage. It says Richardson then urged his girlfriend and two other women, also named in the lawsuit, to attack the plaintiffs.

Browns defensive lineman Desmond Bryant has apologized for his arrest last month, saying the incident was a "mistake" and that "it's really not the kind of person that I am." Bryant, who played for Oakland last season, signed a five-year, $34 million free agent contract on Tuesday with Cleveland.
The 6-foot-6, 311-pounder was arrested on a misdemeanor charge of criminal mischief, and his police mugshot went viral on the internet. Bryant said he's moved on from the incident, and Browns CEO Joe Banner said the team has no concerns about Bryant's character.

The Cleveland Browns have agreed to terms with running back Chris Ogbonnaya on a two-year contract. Ogbonnaya was signed by the Browns in 2011 and started four games. Cleveland has three running backs under contract: Richardson, Ogbonnaya and Montario Hardesty.
Ogbonnaya made one start and played in 15 games last season, usually replacing Trent Richardson on third down. He finished with 24 receptions for 187 yards and gained 30 yards on eight carries. He made a career-high six receptions for 73 receiving yards in a win at Cincinnati, and had a career-long 54-yard reception against the New York Giants.

Barnidge signed with the Cleveland Browns on Wednesday.
Barnidge's decision came one day after the Panthers, his former team, re-signed their other backup tight end Ben Hartsock.

The Chicago Bears have released Davis.
The Bears announced the move Wednesday, one day after signing versatile tight end Martellus Bennett away from the New York Giants. Davis appeared in all 80 games with 35 starts over five seasons for the Bears. He had 47 receptions for 529 yards and 11 touchdowns. In two playoff games, he had two catches for 42 yards and a TD.
