As things currently stand, the Cowboys are unsure what their running back situation will look like for Week 14. Backup Tony Pollard has called himself a “game-time decision,” per ESPN’s Ed Werder (via Twitter). 
Pollard said he suffered a torn left plantar fascia while scoring a touchdown against the Saints in Week 13, via the Dallas Morning News’ Michael Gehlken. The foot injury kept the third-year running back out of practice Wednesday, and Pollard said he is still feeling pain from the tear. With Ezekiel Elliott battling a knee injury, the Cowboys’ high-end backfield setup has taken a hit.
Pollard has enjoyed his best season to date, turning 107 carries into 602 yards and two touchdowns while adding 31 receptions for 259 yards along with a return touchdown. He delivered the Cowboys’ biggest offensive play during their win over the Saints, but that 58-yard dash — the Cowboys’ longest run in four years — proved somewhat costly.
Meanwhile, Elliott is improving from his knee injury, according to Mike McCarthy (via Werder, on Twitter). McCarthy expects both backs to play Sunday, when the Cowboys visit Washington.
The only other RB on the current roster is Corey Clement, who has 9 carries for 20 yards. That’s amazing. I know they just signed Ito, but doubt he’d be ready.
I don’t think Lamb moves back there, but maybe Wilson in an emergency?
