Andrew Luck’s return to the field appears to be going as planned.

The 28-year-old Colts quarterback missed all of last season after he underwent shoulder surgery to repair a torn labrum in January 2017. Luck said Sunday his arm is “responding well” through his first two training camp practices.

“No pain,” Luck told the Indianapolis Star. “Soreness, tiredness, for sure, and stresses (on) my arm that are different. (There are) stresses, shoot, on everybody’s body at this camp that are different.”

Luck said he was rusty during his first practice Thursday. But, he said he has enjoyed the first few days of camp.

“It was fun,” Luck said, “being able to focus on getting better at practice, not just getting through practice and surviving – surviving to the next one.”

Luck is expected to start in the Colts preseason opener against the Seahawks on Aug. 9.
