According to head coach Doug Pederson, Mathews suffered a herniated disc during Thursday's win over the New York Giants. Pederson announced on Friday that Mathews' season was over, but the Eagles made it official on Tuesday night. Mathews finished his second season in Philadelphia with 661 rushing yards and eight rushing touchdowns.
The Eagles enter Sunday's game against Dallas with just two running backs on the active roster -- Darren Sproles and Byron Marshall. Marshall may see the bulk of the carries on Sunday, but the Eagles also have the newly acquired Terrell Watson on the practice squad, who could potential be called up to the active roster to provide depth.
