Indianapolis Colts quarterback Andrew Luck is not close to returning to the practice field because soreness continues to persist in his surgically-repaired throwing shoulder.

The soreness, according to a league source, now has the Colts looking for answers. To that end, Luck plans to see multiple shoulder specialists in the coming days to find the source of the soreness, which prompted the Colts to shut Luck down aft

Luck practiced for two weeks after more than nine months of rehab on the shoulder in which he sustained a partially-torn labrum. But when the soreness developed two weeks ago, the Colts gave Luck a cortisone shot that doctors hoped would cause the pain to subside.
