The Facts: Colts owner Jim Irsay paid tribute to Luck following the quarterback's stunning retirement on Saturday, but he also left the door open for the star pivot to change his mind. "I don't rule it out," said Irsay.

Diehards Line:Alongside HC Frank Reich and GM Chris Ballard, an emotional Irsay said Luck's decision to walk away from football just before the Pro Bowler's 30th birthday broke his heart. "We have nothing but gratitude for him going to battle for us," said Irsay. Luck has battled a calf injury for the past few months, and Ballard revealed the signal-caller first suffered a "ding" last season. The ailment then became an issue while Luck was visiting Europe during the offseason. "You know what was frustrating? He was so excited at the end of the year," said Ballard. Without Luck, Indy will turn to Jacoby Brissett as its starting quarterback. Ballard said he's confident in Brissett's ability to step up. "That locker room loves Jacoby Brissett," said Ballard. "This is a special guy."
