GIbson (toe) is listed as questionable for Sunday's game against the Eagles, John Keim of ESPN.com reports.
There were no reports that Gibson suffered a setback in his return to action in last week's loss to Carolina, but there will inevitably be some level of concern after he was held out of practice Wednesday through Friday. If he doesn't end up playing Sunday, Washington likely would split backfield work between J.D. McKissic and Peyton Barber, as was the case Weeks 14 and 15.
