Linebacker Bobby Carpenter has signed with the New England Patriots.
The former first-round pick of the Dallas Cowboys spent last season with Detroit, where he started three games.
After spending his first four seasons in Dallas, Carpenter was traded to St. Louis for Alex Barron in May 2010. The Rams cut him before the 2010 season, he signed with Miami and played in five games before the Dolphins cut him, and the Lions picked him up to finish the season. He played in every game for the Lions last season, finishing with 29 tackles.
