Conner (shoulder) didn't practice Wednesday, Teresa Varley of the Steelers' official site reports.
At this stage, Conner is looking iffy for Sunday's game against the Bengals. If he's forced to sit out the contest, Jaylen Samuels and Trey Edmunds would be next in line for touches in Pittsburgh's backfield touches, with Benny Snell and Kerrith Whyte candidates to work in reserve.
