Dockett, also named to the Pro Bowl in 2007 and 2009, registered 52 tackles, five sacks and one forced fumble in 15 games this season.
Dockett, a third-round draft pick out of Florida State in 2004, has played his entire NFL career with the Cardinals. He signed a four-year contract extension in September. He had two years left on his previous contract, so the new deal runs through the 2015 season.
