INDIANAPOLIS — Tony Dungy will retire after seven seasons in Indianapolis and Jim Caldwell will take over as Colts coach, one of his assistants confirmed Monday.

Receivers coach Clyde Christensen said Dungy informed the staff of his decision earlier in the day.

"I think there was an intensity in there and it was emotional," he said. "We all felt like it was going to happen one of these years."

Dungy met with players throughout the day to say goodbye.

The move comes a little more than a week after the Colts were eliminated from the playoffs. An afternoon news conference was scheduled to make the announcement.

Repeated messages were left by The Associated Press on Dungy's cell phone.

FoxSports.com was the first to report Dungy's decision.

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 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, which now lives in Tampa. He has always said when he left, he would not return.

"You know, I told my wife I'm sad, but I don't know why I'm sad," Christensen said. "To see a guy be happy and make a good decision, you should be happy. I guess I was just hoping for one more year with him."

Dungy has always listed his priorities as faith, family and football, and returned to coach in 2008 when the Colts opened the new Lucas Oil Stadium only after team owner Jim Irsay agreed to let Dungy use a private jet to commute home.

The decision ends a tenure in Indianapolis during which Dungy became the first black coach to win a Super Bowl. He reached the playoffs all seven seasons, winning five division titles and appearing in two AFC title games.

Dungy finishes his career as the Colts' franchise leader in victories, going 85-27 in the regular season and 7-6 in the playoffs.

But Dungy's teams were also eliminated from the playoffs four times without winning a game, including the past two seasons after winning the Super Bowl — prompting some to speculate that Dungy's indecision may have hurt the Colts' focus.
