Gibson (ankle) was a full participant in Tuesday's practice, Kyle Stackpole of Washington's official site reports.
Washington listed Gibson as a non-participant on its initial Week 12 injury report, but the rookie running back was likely just receiving a maintenance day coming off a 17-touch, 104-yard outing in Sunday's win over the Bengals. His return to full activity Tuesday suggests Gibson should be ready to lead Washington's ground game Thanksgiving Day against the Cowboys.
