Indianapolis Colts quarterback Andrew Luck is seeking treatment on his right throwing shoulder in Europe, according to a report by ESPN.

Luck, who is rehabbing his surgically repaired shoulder and in the process of trying to get it balanced, appears to be seeking non-traditional treatment similar to former Colts QB Peyton Manning, who traveled to Europe to treat a neck injury during his storied career.

Luck practiced briefly in early October before getting shut down and then requiring a cortisone shot to alleviate the continued soreness in his shoulder, which he had surgery on in January. The Colts ultimately ended his season on Nov. 3 when they placed the signal caller on the injured reserve.

Luck threw for 4,240 yards and 31 touchdowns last season, completing a career-best 63.5% of his passes. He last played Jan. 1, 2017.
