​INDIANAPOLIS (WTHR) - Andrew Luck's season is over.

The Colts placed their star quarterback on the Injured Reserve list Thursday, which means he's not allowed to play for the rest of the season.

"We're going to shut his throwing down and we're going to continue rehab, hard rehab," General Manager Chris Ballard said.

"He was frustrated. He's a competitive guy, he knows the impact he has on a Sunday," Ballard continued. "He's a difference-maker. He's one of the best quarterbacks in the league, so he's frustrated."

Ballard said Luck will do his rehab at a couple of different places and is expected to be in and out of the team complex and that they will take a different approach with rehab for his strength.

Ballard said the Colts have to be patient in letting Luck work through this.

As for putting his career in jeopardy, Ballard said: "I'm not getting career-ending from anybody. What we're getting is 'be patient.' Career-ending is putting him on the field before he's ready to play."

WTHR.com's Bob Kravitz confirmed earlier this week that Luck wouldn't be returning to practice anytime soon, and was even scheduled to see a specialist.

This past summer, owner Jim Irsay said he expected Luck to be ready for the season opener in Los Angeles against the Rams. Later, after a preseason game at Lucas Oil Stadium, he said Luck might miss a few games to start the season, but then would return.

He did return to practice on Oct. 4. After practicing four times with limited action, he got pulled back off the practice field Oct. 18 and was given a cortisone shot to deal with inflammation and soreness in his throwing shoulder.

Luck's injury originally occurred during a come-from-behind win at Tennessee in September 2015.

He missed nine games that season, two with the injured shoulder and seven with a lacerated kidney. Despite playing through the pain in 2016 and missing one game with a concussion, Luck had perhaps his best statistical season before opting for surgery.

He completed a career-high 63.5 percent of his passes, threw for 4,240 yards with 31 touchdowns and 13 interceptions.

If Luck is ready to go for the 2018 season opener, he would have gone more than 20 months between taking regular-season snaps.
