Edmonds (back) practiced on a limited basis Thursday, Darren Urban of the Cardinals' official site reports.
Both of the Cardinals' top running backs are at less than 100 percent health at the moment, but Edmonds at least has been able to log some on-field work this week. On the other hand, James Conner (heel) was listed as a non-participant on a fifth straight practice report and may be poised for a second consecutive absence Sunday in Dallas. If that comes to pass, Edmonds again would be Arizona's unquestioned No. 1 RB -- assuming he's active -- which translated to 24 touches for 127 yards from scrimmage and one TD this past Saturday versus the Colts.
