Indianapolis Colts quarterback Andrew Luck is in Europe seeking treatment on his surgically repaired right shoulder, sources tell ESPN's Mike Wells and Chris Mortensen.

The Colts placed Luck on the injured reserve list Nov. 3, ending his season. The decision came after Luck visited with doctors to ask why he was still having soreness in his right shoulder. It also ended months of speculation about whether the quarterback would play this season after having surgery in January.

Luck practiced on Oct. 4 for the first of two times since December 2016. Then he practiced two more times before he was shut down and given a cortisone shot to see if the soreness would subside.

Colts GM Chris Ballard, as he has consistently said since April, will not put a timetable on Luck's return. That means there's no guarantee the quarterback will take part in offseason workouts in the spring.
