2:28pm: In addition to Westerman, the Browns have also struck an agreement to sign linebacker Edgar Jones, according to agent Marc Lillibridge of Pro Football Syndicate (via Twitter). Although he played 74 defensive snaps last season in Dallas, Jones has played primarily on special teams during his seven-year career with the Ravens, Chiefs, and Cowboys.
1:39pm: Free agent linebacker Jamaal Westerman has agreed to a deal and will sign with the Browns, according to his representatives at Eastern Athletics Agency (Twitter link).
Westerman, 29, spent his first three seasons with the Jets, but has bounced around among several teams in the last two years. The Rutgers product appeared in a handful of games for the Colts and Cardinals in 2012, then played for the Bills and Steelers last season. In 12 contests for Buffalo, Westerman contributed on defense and special teams, logging nine tackles and splitting a sack.
No roster move is necessary to make room for Westerman, since the team already has multiple open roster spots, but the Browns are cutting running back Jourdan Brooks and wideout Kenny Shaw anyway, per Mary Kay Cabot of the Cleveland Plain Dealer (Twitter link). The series of moves will leave the club with 87 players on its 90-man roster, so more signings figure to follow at some point.
