Irving, TX (SportsNetwork.com) - The Dallas Cowboys made it official on Thursday, signing Jason Garrett to a new five-year contract agreement to remain the Dallas Cowboys' head coach.
The pact will pay the Princeton product $30 million for the duration.
Garrett led the Cowboys to the playoffs this season for the first time since 2009. The Cowboys captured the NFC East title with a 12-4 record -- their best since going 13-3 in 2007 -- and then beat the Detroit Lions in the wild- card round before losing to the Green Bay Packers in the divisional round last Sunday.
The 48-year-old Garrett became the Cowboys' interim head coach in the middle of the 2010 season, replacing Wade Phillips, who was fired following the team's 1-7 start.
Dallas finished the season 5-3 under Garrett, earning him the job on a full- time basis.
The Cowboys went 8-8 in each of the next three seasons, losing Week 17 games to division opponents to miss the playoffs each time.
Dallas also announced new contracts for defensive coordinator Rod Marinelli and new offensive coordinator Scott Linehan. Linehan takes over for Bill Callahan, who has moved on to become offensive line coach with the rival Redskins.
In addition, Garrett said he was "in a process of finalizing" the remainder of his coaching staff.
