Indianapolis Colts quarterback Carson Wentz returned to practice Monday after undergoing ankle surgery earlier this month.

At the training camp, Wentz told reporters he was optimistic that he would be ready for the season opener against the Seattle Seahawks in less than three weeks.

While Wentz suggested that he wanted to be under center for the game on September 12, he insisted that his doctors would hold the final decision.

“I’m optimistic, but we’ll see how it responds,” Wentz said, as quoted by WISH-TV’s Olivia Ray. “It’s gonna be up to the doctors, for sure. At the end of the day, as long as there’s nothing that I can do to injure myself and make it worse, I know I’ve played through a lot worse. But it’s gonna come down to what the doctors say.”

Meanwhile, the Colts refused to put a timetable for his return. He was allowed to participate in the team’s Monday practice as a limited participant. Several reporters, however, noted that the quarterback was fully involved on the field.

“I’m probably a little bit surprised,” coach Frank Reich said after practice, according to Ray. “It feels to me like we are maybe a week ahead of schedule.”
