Terms of the deal weren't disclosed.
Furrey, who broke into the league with the St. Louis Rams in 2003, is a six-year NFL veteran, making him one of the Browns' most-experienced receivers. David Patten, who also came to Cleveland this offseason, has played in 12 NFL seasons, and Donte' Stallworth, who's facing DUI manslaughter charges in Miami, is a seven-year veteran.
Furrey's best season came in 2006, when he caught 98 passes -- second-most in the league -- for 1,086 yards and six touchdowns for the Lions. The previous season, Furrey showed his versatility by starting 11 games at safety for the Rams and returning punts.
