An assistant coach confirms that Tony Dungy is retiring after seven seasons in Indianapolis and that Jim Caldwell is taking over as Colts coach.

Receivers coach Clyde Christensen says Dungy informed the staff
of his decision earlier in the day and is meeting with players to
say goodbye.

The team has called a late-afternoon news conference to announce
the move, which comes a little more than a week after the Colts
were eliminated from the playoffs.

The plan to have Caldwell replace Dungy was put in place last
year when the coach pondered retirement. Caldwell joined Dungy's
staff in Tampa Bay in 2001, then moved with Dungy to the Colts in
2002 and was the quarterbacks coach. A year ago, Caldwell was
elevated to associate head coach though he continued to coach QBs
Peyton Manning and Jim Sorgi.

Dungy has spent the past five years debating whether to leave
football, each year taking about a week to meet with his family,
who now live in Tampa. He has always said when he left, he would
not return.
