Pittman (back/finger) remained sidelined at practice Friday, James Boyd of The Athletic reports.
Pittman also missed sessions Wednesday and Thursday, and his continued absence Friday doesn't bode well for his chances of playing Sunday against the Bills. If Pittman ends up being unavailable for the contest, the Colts' Week 10 wideout corps would be in line to be led by Josh Downs and Alec Pierce, with Ashton Dulin and Adonai Mitchell mixing in.
