The New England Patriots signed veteran defensive tackle Andre Neblett.
Neblett has a previous stint with the Carolina Panthers and recorded 40 tackles and three sacks in the past three seasons. He was suspended four games last season for violating the NFL performance-enhancing drug policy.
He was cut by the Tampa Bay Buccaneers before the regular season.
The Patriots re-signed linebacker Ja'Gared Davis and safety Kanorris Davis to the practice squad.
