The Patriots continued to add veteran D-linemen, agreeing to terms with former Redskins DE Andre Carter on Sunday.
Carter tweeted, "I am proud to announce that I will be playing for the New England Patriots for the 2011 season."
ESPN Boston's Mike Reiss confirmed the move, but the team has yet to announce it.
Carter spent the last five seasons with the Redskins after beginning his career with the 49ers. He played in all 16 games last season with five starts and recorded 2½ sacks — his lowest sack output since 2004 when he played in just seven games.
Carter has 66 career sacks. The Patriots have added Mark Anderson, Shaun Ellis and Albert Haynesworth to the D-line so far this offseason.
The team announced that it released CB Thad Turner, who finished last season on the Patriots' practice squad.
The way we see it
Bill Belichick won't admit that the team is moving to a 4-3 next season, but he is loading up on veterans who have plenty of experience getting after the quarterback from the defensive line, something the team lacked in 2010. With the Patriots you can still expect a variety of fronts, but he has better personnel on the D-line to rush the passer.
