Dallas Cowboys running back Felix Jones has a sprained ligament in his left knee..
His status for the upcoming game against Denver is uncertain.
The former Arkansas start had an MRI today after getting hurt in the Monday Night Football win over Carolina.
He rushed for 94 yards, and had another 20 on a catch out of the backfield.
Jones was making his first career start, replacing injured starter Marion Barber.
Barber may be back to play against the Broncos.
