The rehabilitation process, however, hasn't prevented Luck from tossing light passes Wednesday morning with children during his annual "Change the Play" event, which encourages kids to make healthier choices about exercising and nutrition.
And following each toss and throwing motion, Luck continues to feel no pain in his surgically repaired shoulder.
The quarterback will continue rehabilitation during the break, and then get together with some of the Colts receivers for throwing sessions, according to the Indianapolis Star.
Luck has endured a long road of recovery, and his goal when the Colts kick off training camp on July 26 is to continue to get stronger and improve heading into the regular season.
"I've put a lot of work in," Luck told the Indianapolis Star. "And it's paying off. My goal is not to get to training camp and plateau. It's to keep getting better and better."
