Andrew Luck took part in practice on Wednesday for the first time this season, but has already been ruled out for Sunday's game against the San Francisco 49ers.

Luck will take part in individual drills again on Friday after using Thursday as a rehabilitation day.

The Indianapolis Colts quarterback revealed that his surgery was a posterior labrum repair, which traditionally takes longer to heal than other types of labrum procedures.

"I'll definitely play this year," Luck said when asked if he'll play this season. "No question."

Luck, however, didn't offer a timeline for when he'll return to the field.

"There have not been any setbacks at all ... I do feel like I've progressed," he said. "We've never put out a schedule, per say. There have been goals and they've been time-oriented with dates. And we've managed to meet those goals. But as far as a schedule, I think that's a dangerous word to use in regards to coming back as a quarterback with a throwing-shoulder surgery."
