Pittman (back) was present but not participating in Friday's practice, according to Nate Atkins of The Indianapolis Star.
Pittman practiced fully Thursday, so it's possible that his non-participation Friday is rest-related rather than indicative of a setback. The Colts' upcoming injury report thus is slated to reveal the Week 7 game statuses of Pittman and fellow WRs Josh Downs (toe) and Alec Pierce (shoulder).
