Andrew Luck shocked the world when he announced his decision to retire from the NFL on Saturday, but Colts owner Jim Irsay hasn't given up hoping he'll see the quarterback in an Indianapolis jersey down the road.

Irsay spoke with reporters following Luck's announcement and gave his opinion on if Luck might return to the team.

"I don't rule it out because as quickly as this thing descended on us and mysterious as it was, it could leave the same way," Irsay said. "That's just a fact. It's very hard to measure sometimes our human experience and we all perceive life from our chair. I would say it's possible."

But Irsay isn't banking on the slim chance Luck will have a change of heart.

"We know we have to get on and play. We are focused on having a great season. It's possible but no one knows and he would be the first to say it. Only time will tell."

Luck, 29, was a Pro Bowl player in four of his six pro seasons and is fresh off a 2018 NFL Comeback Player of the Year award. He led the Colts to a 10-6 record last season and into the second round of the playoffs, so he'll certainly be hard to replace. 

Indianapolis is just thankful for the good times it had with him calling the shots.

Coach Frank Reich only had positive things to say about wh

at Luck brought the Colts since being selected first overall in the 2012 NFL Draft.

"Being in that room with him for the last 18 months was just the experience of a lifetime," Reich said. "You know, a true competitor in every sense of the word, a great teammate and just one of the truly unique players to ever put on an NFL uniform and certainly, to wear that horseshoe proud. So, for the coaching staff in that locker room, just getting a chance to work with this guy every day was incredible."

Now Indianapolis is focused on moving forward with Jacoby Brissett, who threw for 3,098 yards and 13 touchdowns with the Colts when Luck sat out for all of 2017 to recover from a shoulder injury.

"There's a saying in football that everyone knows and everybody lives by, it’s next man up and even though this situation is unique, no one is exempt," Reich said.

The Colts will kick off 2019 against the Chargers in Los Angeles on Sept. 8, with Brissett under center.
