Colts running back Trent Richardson remained sidelined from the media availability portion of Friday practice with a hamstring issue, according to the Indianapolis Star. His status for the Sunday game against Pittsburgh therefore becomes more in doubt.

Richardson is coming off one of his best games since joining the Colts early last season. He rushed for 77 yards on a season-best 5.5 YPC and added four receptions for 41 yards in the thumping of Cincinnati.
