McFadden (groin) was listed as a non-participant on Monday's injury report, according to the Cowboys' official site.
Monday's session was merely a walk-through, so McFadden could make a return to drills as early as Tuesday. His workload over the last month warrants a rest from time to time, as he's received between 20 and 32 touches in five consecutive games. As Thursday's outing against the Panthers approaches, expect his practice participation to confirm that he's again the Cowboys' No. 1 back.
