Edmonds may have suffered a high-ankle sprain during Sunday's win over the 49ers, Ian Rapoport of NFL Network reports.
Edmonds was forced out of Sunday's divisional win after injuring his ankle during Arizona's first play. The results of Monday's MRI will confirm the severity of his injury, but if he's indeed suffered a high-ankle sprain the Cardinals likely will place him on injured reserve. Rapoport notes that such injuries generally carry a recovery timetable of 4-to-6 weeks. James Conner will operate as Arizona's lead running back if Edmonds is forced to miss any amount of time, while Eno Benjamin would be a candidate to step into the No. 2 role.
