Details of the contract, confirmed by a team source, were not yet available.
Ivy is not at the same performance level as Rolle or McAlister, but he is one of the best nickel cornerbacks in the league and a solid part-time starter. The Ravens have signed free agents Domonique Foxworth and Chris Carr to rebuild the cornerback position, but the loss of Ivy is a fairly significant one.
The much-traveled Ivy began his career with New England in 1999 as an undrafted free agent from Oklahoma. He played for the Patriots as a rookie, and also has been with Tampa Bay (2001-2004), St. Louis (2005), and Baltimore (2006-2008).
Although he started 11 games in 2007, Ivy has settled into the nickel role and likely will assume the same role for the Browns. He has played in 102 games with just 21 starts. For his career, Ivy has 278 tackles, interceptions and 23 passes defensed.
Last season with the Ravens, Ivy appeared in all 16 games with just one start, and had 52 tackles, no interceptions, and three passes defensed.
