The New England Patriots have activated defensive lineman Jermaine Cunningham to the 53-man roster and signed wide receiver Kamar Aiken and defensive back Malcolm Williams from the practice squad.
The team also released defensive lineman Ron Brace.
Cunningham has played in 11 games with three starts in 2012 and has 24 tackles, 2½ sacks, and two fumble recoveries. He joined the Patriots as a second-round (53rd overall) draft pick out of Florida in 2010.
The Patriots (11-4) host the Miami Dolphins (7-8) in the regular-season finale on Sunday.
