Adam Schefter of ESPN suggests that it "would be a mild upset" if Conner (shoulder) was available to play Sunday versus the Bengals.
In his return from a two-game absence for a Thursday night loss to the Browns in Week 11, Conner aggravated an AC joint injury in his right shoulder, which limited him to just 13 offensive snaps before he was pulled from the contest. If he's unable to suit up this weekend, added backfield work would be on tap for Jaylen Samuels, Trey Edmunds and Benny Snell.
