The most infamous shoulder in sports is back at it again. Andrew Luck, once the most coveted young quarterback in the game, missed the entire 2017 season and has only played in a combined 22 games over the last three seasons. The Indianapolis Colts and their fans just want to know what's going on with their franchise face's shoulder.

Though some words of encouragement have been uttered as of late, there's still no official timetable for his return, according to Mike Wells of ESPN.

“Colts general manager Chris Ballard, while optimistic, has maintained his stance that there’s no timetable on Luck’s return. He has not thrown a football since the middle of October. He spent six weeks in the Netherlands rehabbing his shoulder in November and December. What’s key at this point for Luck, who said he expects to take part in the team’s offseason workouts in April, is that a second surgery is not needed on his shoulder. The quarterback, who missed all of the 2017 season, is working with a throwing expert in California.”

Of course, it's tough to pinpoint the exact injury Luck's dealing with. Why? Well, doctors haven't truly been able to diagnose it properly, so how could we?

Over his first three seasons, the Colts were fortunate to represent the envy of all 31 other NFL franchises. As a can't-miss stud, Luck started all 16 games in each of those first three while making the Pro Bowl each time. In 2014, he threw for 4,761 yards and 40 touchdowns while leading his Colts to the AFC championship game.

Luck will hope to get back to his dominant ways with new head coach Frank Reich beginning this summer.
