Deaderick, a seventh-round draft choice out of Alabama, dressed for 10 games this season (four starts). Coaches credited him with 17 tackles and he had two sacks.
Deaderick's playing time had tailed off considerably since Nov. 25 at Detroit, when he was inactive after a stretch of seven games in which he dressed. Entering the postseason, he projected as a backup adding depth along a defensive line that has been hit with injuries.
Meanwhile, a former teammate of Deaderick's at Alabama, defensive lineman Lorenzo Washington, was released from the Patriots' practice squad on Monday.
The Patriots have battled injuries along the defensive line, with Myron Pryor (back/eye), Mike Wright (concussion) and Ron Brace (concussion/elbow) all missing time in recent weeks. Brace was placed on season-ending injured reserve Monday with an elbow injury.
