The Browns were awarded linebacker Matt Roth off waivers from Miami Wednesday, a move aimed at plugging the gaping hole on defense left by starters D'Qwell Jackson (pectoral muscle) and Eric Barton (neck), who've recently been sidelined with injuries.
Roth was originally signed by the Dolphins in the second round (46th overall) in the 2005 draft out of Iowa.
In five seasons with Miami, Roth has played in 64 games (23 starts), totaling 158 tackles, 12.5 sacks, five passes defended and six forced fumbles. His best season came last year when Roth moved from defensive end to linebacker, but he eventually lost his starting job to University of Akron product Jason Taylor.
Recently, Miami coach Tony Sparano said Roth was "really impressive" in the Dolphins 25-23 win over Tampa Bay on Nov. 15th. But it's been a frustrating season for Roth, who missed training camp and the first five games of the season with a groin injury.
