Conner (ankle) didn't practice Thursday, Josh Weinfuss of ESPN.com reports.
Since Chase Edmonds went down early with a high-ankle sprain in a Week 9 win at San Francisco, Conner has averaged 21.8 touches for 114.4 yards from scrimmage per game while scoring eight total TDs over five contests. Conner's workload has ranged between 76 and 96 percent of offensive plays during that span as the Cardinals' unquestioned lead back, but he also sustained an ankle injury while getting tackled near the conclusion of Monday's loss to the Rams, per Darren Urban of the team's official site. Arizona designated Edmonds for return from injured reserve last Thursday, so the Cards could be status quo in the backfield as early as Sunday in Detroit if he's activated and Conner is able to gut out his current health concern.
