Prescott (ankle) will be a full participant in Wednesday's joint practice with the Rams, Jon Machota of The Athletic reports.
Prescott was given a precautionary day off last Friday due to ankle soreness, but the issue is no longer hampering him. If the Cowboys elect to play key starters during Saturday's preseason game against the Raiders, Prescott should be in line to play after having sat out the team's exhibition opener against the Rams. Prescott is still working without star wideout CeeDee Lamb at practice, as the No. 1 receiver remains away from team activities amid an ongoing contract dispute.
