Luck has cleared numerous obstacles since missing the 2017 season with a right shoulder injury, and he will apparently check another box in the coming weeks.
Luck wasn't placed on the physically unable to perform list to start training camp, and general manager Chris Ballard recently said Luck will practice without limitations.
"I feel like I'm in a much better place," Luck told reporters Wednesday. "I'm the best I've felt in a long, long time. I've got work to do still. I've got things I have to do, things I have to go out and prove to myself. But yeah, I feel a lot better."
Nevertheless, the Colts are likely to play it smart throughout training camp by monitoring repetitions and allow built-in off days for Luck.
The Colts' franchise quarterback hasn't experienced live game action since the end of the 2016 season, but the team planning to utilize Luck in preseason action signals confidence he will be back under center for the start of the regular season.
