Ian Rapoport of NFL Network reported the diagnosis Monday:
On Sunday, Eagles coach Nick Sirianni told reporters after the game that he doesn't believe Sanders broke anything.
Sanders had six carries for 30 yards and one reception for minus-three yards before exiting. Boston Scott and Kenneth Gainwell shared the workload out of the backfield.
In his third NFL season, Sanders has 418 yards from scrimmage (300 rushing, 118 receiving) this year. His usage has been a point of contention among some fans considering his 57 carries entering Sunday was only slightly more than quarterback Jalen Hurts had (53).
The Penn State product missed four games last season because of injury.
The Eagles will likely rely on Gainwell to serve as their top running back should Sanders remain out of the lineup, while Scott could see his influence grow as well.
