The Patriots announced four roster moves Monday afternoon: fourth-year defensive lineman Brandon Deaderick and receiver Andre Holmes were released; also, rookie free agent OL R.J. Mattes was signed. New England also made the Tyronne Green deal official.
The release of Deaderick is a bit of a surprise. A a 2010 seventh-round pick out of Alabama, Deaderick played in 14 games last season with five starts. He was credited with 18 tackles, one sack, two forced fumbles, and a pass break-up.
Deaderick had played in 20 games over his first two seasons, starting five games in 2011 and four in '10.
Holmes was signed to the practice squad late last season.
Mattes was a four-year starter at guard and tackle while at North Carolina State. He is listed at 6 feet 6 inch, 313 pounds.
