Former Colts coach Tony Dungy will be a guest on the "Late Show with David Letterman" on Thursday night.
Dungy retired after 31 years in the NFL as a player and coach. He's now promoting a new book, "Uncommon: Finding Your Path to Significance."
His straight, deadpan delivery makes him a good guest for Letterman, whose roots are in Indiana.
Also slated to appear: Actress Renee Zellweger and Graham Nash, who will sit in with Paul Shaffer and the CBS Orchestra.
