But with or without the explosive running back, the Dallas Cowboys will pick up their sixth win of the season against Andy Reid's beleaguered unit.
The Cowboys have been a bad football team this season, plain and simple. Saying they have been inconsistent would actually be giving them too much credit.
They are also coming off one of their worst defensive performances of the season, allowing Robert Griffin III and the Washington Redskins to carve them up in a 38-31 loss.
But as bad as the Cowboys have been, the Eagles have been worse.
After the 30-22 loss to the Carolina Panthers last week, the Eagles have now lost seven-straight games—the worst stretch of Reid's tenure in Philadelphia.
They, like the Cowboys, have no clue how to stop the pass.
They have ceded 7.7 yards per pass attempt this season (26th in the NFL), and they just allowed Cam Newton to throw for 306 yards and two touchdowns with no interceptions.
The Cowboys have a better passing game than the Eagles, and that will be the difference in Sunday's NFC East clash—no matter who starts in the backfield for Dallas.
Who will win on Sunday?
Eagles rookie Nick Foles has averaged 5.5 yards per pass attempt in three games this season while tossing one touchdown to three interceptions.
When he took over for the concussed Michael Vick against the Cowboys in Week 10, he averaged 6.8 yards per attempt while posting one touchdown and one interception. His interception in that game was returned 47 yards for a touchdown by Cowboys cornerback Brandon Carr.
In most cases, given the Cowboys' meltdown against the Redskins in Week 12, they would be headed for another defeat.
But, given the Eagles' ailing offense (which will be without LeSean McCoy this week, mind you), the Cowboys will put up enough points to notch their third home victory of the season.
