The Indianapolis Colts officially introduced Jim Caldwell as their new head coach on Tuesday, announcing the signing of a four-year deal.

Caldwell replaces Tony Dungy, who decided to retire after 13 consecutive seasons as an NFL head coach, including the last seven with Indianapolis.

Caldwell, who turns 54 on Friday, has been with the Colts since 2002. He served as quarterbacks coach, adding the title of assistant head coach three years later, giving him familiarity with the team and its star player, Peyton Manning.

The new head coach was previously with Dungy in Tampa Bay as a quarterbacks coach, and has held coaching jobs with several schools, including Penn State and Colorado. In his only head coaching experience, he went 26-63 in eight seasons with Wake Forest.

President Jim Irsay would not reveal Caldwell's salary but said it was in line with what first-time coaches make.
