Andrew Luck confident he will be ready to return for Indianapolis Colts in 2018

Andrew Luck says his throwing shoulder feels stronger and he hopes to participate in the Indianapolis Colts' offseason workouts.

The three-time Pro Bowl quarterback returned to the team complex Friday after spending multiple weeks rehabbing in the Netherlands.

Luck says he had no additional medical procedures done while he was out of the country. He has not yet resumed throwing and insists he is confident additional surgery will not be necessary.

Luck had surgery in January to repair a partially torn labrum in his right shoulder, did not start throwing a football until October and then was shut down because of lingering pain.

In November, after seeking additional opinions about treating the injury, he went on season-ending injured reserve.

He is confident he will have recovered in time to begin the 2018 season.

"I don't see that being in jeopardy at all," Luck told reporters.
