Andrew Luck's surgically-repaired right shoulder is "healing tremendously," according to Indianapolis Colts owner Jim Irsay.

The quarterback had surgery five months ago.

"This [surgery] has been a positive thing, not a negative thing or anything like that," Irsay told season-ticket holders. "He was really struggling going through the process of being ready to play [each week last season]. This was, quite frankly, not that complicated of a surgery. This was a simple labrum repair. There are a lot of other things that could have been involved with this surgery that weren't."

Irsay didn't provide a timetable for when Luck will begin throwing a football, but he has said in the past that the quarterback will be ready for the start of the season.
