Conner (heel) was listed as a non-participant on Tuesday's estimated injury report, Josh Weinfuss of ESPN.com reports.
Conner tended to an ankle issue last week before welcoming back Chase Edmonds (ankle) to the backfield following a four-game IR stint. The pair split the RB reps this past Sunday at Detroit, with Conner logging a 42 percent snap share and 10 touches and Edmonds turning 40 percent of those plays into six carries. Conner now is dealing with a heel injury, so his status again will need to be watched to get a sense of his availability for Saturday's game against the Colts.
