Andrew Luck limited at practice with shoulder injury for 2nd consecutive day

Indianapolis Colts quarterback Andrew Luck was a limited practice participant for the second consecutive day Thursday because of an injury to his throwing shoulder.

As he did Wednesday, Luck primarily watched as reserve quarterbacks Matt Hasselbeck and Alex Tanney took reps with the offense, and made no throws during the portion of practice open to the media, according to Zak Keefer of the Indianapolis Star.

It's unclear when Luck suffered the injury, but head coach Chuck Pagano said Wednesday that he has "supreme confidence (Luck) will play" Sunday against the Jacksonville Jaguars.
