Andrew Luck has cortisone shot in shoulder, Colts confirm he won't practice this week

Andrew Luck's hopes of an imminent return have suffered a setback with the Indianapolis Colts again setting no timetable for his comeback.

The Colts have been without their star quarterback all season after he had offseason surgery to correct a long-term issue with his right throwing shoulder.

Luck had returned to practice a fortnight ago, but Colts general manager Chris Ballard said on Wednesday that he would be shut down this week.

Ballard confirmed Luck was suffering soreness in his shoulder and had been given a cortisone shot to help with pain management.

However Ballard hopes the setback will not prove to be a lengthy one and joked "the sky is not falling" when first announcing that Luck would not practice this week.

"It's natural that there's going to be some pain and soreness when you're rehabbing an injury," Ballard said.

"We're going to try and shut him down and calm it down right now."
