Conner (heel) didn't practice Wednesday, Darren Urban of the Cardinals' official site reports.
Conner has yet to practice due to the heel issue that he picked up coming out of the Cardinals' Week 15 loss to the Lions. Last week, his availability came down to the wire before he was ultimately inactive ahead of the Cardinals' loss to the Colts. Head coach Kliff Kingsbury said Wednesday that Conner will be in a similar situation this week, with the running back's status likely coming down to a game-time call ahead of a 4:25 p.m. ET kickoff Sunday in Dallas, according to Urban. Conner would do himself well by mixing into drills Thursday and/or Friday, but it should be noted that position mate Chase Edmonds (back) was limited by in Wednesday's session, placing a cloud over both of the top two options out of the Arizona backfield.
