Indianapolis Colts quarterback Andrew Luck's absence from the practice field due to a left calf injury will last at least another week, coach Frank Reich said Saturday.

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

Luck missed the Colts' OTAs and minicamp, and has only practiced three days in training camp since originally injuring his calf back in April. He approached the Colts on their off day on July 29 and said he wanted to stop practicing until he felt his calf was 100 percent.

Luck has been a participant in the team's walk thru's, where he's taken most if not every one of the snaps in an attempt to stay up to speed with the offense. He has also been working with throwing coach Tom House.
