Andrew Luck will be out of the Indianapolis Colts training camp for another week while he deals with a left calf injury.

The Colts’ quarterback has been battling the injury since April. He already missed the Colts’ OTAs and minicamp and has been limited over three days of training camp. The 29-year old told the team on Monday that he wanted to sit out until he is back to full health.

"I feel good about where we're at," head coach Frank Reich said. "Just ramping it up from last week. That was so productive last week that we feel we're on the right track.”

"When (Luck) has his throwing sessions, there is some movement in there, and we are progressing in that."

Luck will continue to take snaps during walk-throughs so that he and his offense can maintain chemistry.

The four-time Pro Bowler will not take part in the team’s preseason opener against the Buffalo Bills on August 8 as well as the Week 4 exhibition game.

With Luck not participating in drills, Jacoby Brissett has been behind centre with the first unit.

Luck believes that he will be ready for the opening week of the regular season.
