Emonds underwent an MRI on Monday that revealed a high-ankle sprain, Adam Schefter of ESPN reports.
Edmonds suffered his injury early in Sunday's Week 9 win over the 49ers and is expected to miss 3-to-4 weeks while he recovers, according to Ian Rapoport of NFL Network. It appears likely that the 25-year-old will require a stint on injured reserve, and his absence should create more opportunities for James Conner and even Eno Benjamin.
