TEMPE, Ariz. (AP) -- The Arizona Cardinals have signed Pro Bowl defensive tackle Darnell Dockett to a four-year, $48 million contract extension with $30 million guaranteed.

Dockett had two years left on his previous contract, so the new deal keeps him under contract through the 2015 season. A third-round draft pick out of Florida State in 2004, Dockett has developed into one of the best at his position entering his seventh NFL season as the high-spirited leader of the Arizona defense.

He had a career-high nine sacks in the 2008 regular season. His seven sacks last season were the most for an NFL defensive tackle.
Dockett's three sacks against the Pittsburgh Steelers two seasons ago tied Reggie White's Super Bowl record.

Dockett has started 81 consecutive games going into this season.
