According to Adam Schefter, Andrew Luck has informed Colts owner Jim Irsay that he is retiring.
Team officials did not immediately confirm the report.
The 29-year-old quarterback was the No. 1 pick in the 2012 draft out of Stanford.
It's stunning news for a Colts team that went to the second round of the playoffs last season and that, in the eyes of many, had a Super Bowl-caliber roster in 2019. He recently won Comeback Player of the Year in 2018 after missing all of 2017 with a shoulder injury.
But in March, he suffered a strained left calf, was held out of all of the team's offseason workouts and returned on a limited basis for three practices at training camp in July. He confirmed the decision in a press conference after the Indianapolis Colts' preseason game tonight.
Luck was in the middle of a five-year, $123 million contract extension he signed with the Indianapolis Colts in June 2016.
In 86 career regular-season games, the 6-foot-4, 240-pounder from Stratford, Texas, had a 53-33 record, completing 60.8% of his passes for 23,671 yards and 171 touchdowns, against 83 interceptions.
As far as the Colts are concerned, they are absolutely finished this season.
'This is not an easy decision. "Honestly, it's the hardest decision of my life", Luck told reporters on Saturday. "But it is the right decision for me", he said. He's a great quarterback. We have some good skill players.
ESPN analyst and former National Football League offensive lineman Damien Woody made the point that we will probably see a documentary on Luck's decision one day.
"Jacoby Brissett is a winning football player in this league", Ballard said Saturday.
"I'll be honest. It hurt", he said.
