The Raiders signed veteran DE Andre Carter, the team announced Wednesday. They also cut second-year OT Joe Barksdale.
Carter started all 14 games he played last season for the Patriots and had 52 tackles, 10 sacks and two forced fumbles. He suffered a torn quad in Week 14, ending his season.
There had been talks of Carter returning to the Patriots, but the two sides never agreed on terms.
In his 11 seasons, Carter has 76 career sacks. He played for the 49ers from 2001-05 and the Redskins from 2006-10.
Barksdale was a third-round pick in 2011. He appeared in all 16 games last season but had not appeared in a game yet in 2012.
