Andrew Luck has stopped throwing passes for now, and it’s not yet clear when he’ll resume.

On Wednesday, Indianapolis Colts general manager Chris Ballard said the team has instructed the star quarterback to take a break from throwing after developing soreness in his surgically repaired throwing shoulder.

“The doctors and the trainers have decided — they’ve given him a cortisone shot to kind of take away some of that inflammation that’s been happening,” Ballard said. “In terms of the rehab, it’s been going well.”

Ballard explained some soreness was expected as Luck continued to work his way back from a partially torn labrum in his right shoulder.

But the news came as a surprise after two straight weeks of promising signs.

Since having surgery in January, Luck missed all of the team’s offseason workouts, all of training camp and the entire preseason before finally being cleared to practice Oct. 4. He did some light throwing that day and was told he could throw every other day.

Last week, Luck ramped up the rehab work. He was throwing passes of 35 to 40 yards with increased velocity and was scheduled to run the scout team as Indy (2-4) prepared for Monday night’s matchup at Tennessee.

Backup Scott Tolzien was benched 31/2 quarters into the season opener, and coach Chuck Pagano selected Jacoby Brissett as the starter in Week 2.

Brissett has produced mixed results, going 2-3 as the starter with Indy struggling to maintain second-half leads. The Colts’ only wins have come against the NFL’s two remaining winless teams — Cleveland and San Francisco.
