Indianapolis Colts quarterback Andrew Luck hasn’t been cleared to throw yet after undergoing shoulder surgery in January, head coach Chuck Pagano said Tuesday.

Luck completed 63.5 percent of his passes for 4,240 yards and 31 touchdowns against 15 interceptions in 15 games last season, but underwent surgery after experiencing discomfort.

Pagano said he’s relying on the Colts’ medical staff for more information on when Luck can return to the field.

“I’m not a (doctor), I’m following the protocol and he’s going through rehab and we’ll listen to our trainers,” Pagano said to ESPN’s Mike Wells. “He’s staying the course and staying with the process. So when it’s time he’ll start (throwing).”

Scott Tolzien, Stephen Morris, and Phillip Walker are behind Luck on the depth chart, all of whom would be untenable long-term options in the event that the Colts’ superstar can’t play during the regular season.
