Indianapolis Colts quarterback Andrew Luck, who went on season-ending injured reserve last week, continues to look for answers about his surgically repaired right shoulder.
Sources told ESPN's Mike Wells and Chris Mortensen that the 28-year-old Luck is in Europe seeking treatment on his throwing shoulder.
The Colts decided to place Luck on the IR list Nov. 2 following his visit with doctors to ask why he still had soreness in his right shoulder. The move ended months of speculation about whether Luck would play this season after he underwent surgery in January.
Luck finally returned to practice on Oct. 4 for the first of two times since December 2016. He practiced two more times before being shut down by the team as he continued to have shoulder soreness.
Luck, who has not taken a snap in a game since Week 17 last season, underwent surgery to repair a torn labrum on Jan. 15.
The Colts selected Luck with the No. 1 overall pick in 2012 and he started every game during his first three seasons. The Colts went to the playoffs, including the AFC Championship Game in 2014, in each of those seasons.
Luck was coming off perhaps his best overall performance in his six-year NFL career after playing in just seven games in 2015 due to a variety of injuries that included an abdominal muscle tear. In 2016, he completed 346 of 545 passes (63.5 percent) for 4,240 yards with 31 touchdowns to 13 interceptions, and also ran 64 times for 341 yards with two more scores.
For his career, the three-time Pro Bowler has completed 1,570 of 2,651 passes (59.2 percent) for 19,078 yards with 132 touchdowns to 68 interceptions, and has 286 rushing attempts for 1,442 yards and 14 more TDs.
