It's what everyone's been speculating, but foxsports.com is the first to report it. Jay Glazer says Tony Dungy is retiring as coach of the Colts.
The development means associate head coach Jim Caldwell, who coaches the team's quarterbacks, will take over the post in a predetermined succession plan.
We'll monitor through the day, hopefully be in position to hear or see the press conference live and be back with reaction and a look ahead.
