The Dolphins announced Monday that Achane (knee) has been designated for return from IR, Adam Schefter of ESPN reports.

EDGE Analysis

Achane will be eligible to retake the field as soon as Sunday's contest against the Raiders, but Miami does have a 21-day practice window in which to evaluate him. The electric rookie will resume working alongside veteran Raheem Mostert in the Dolphins backfield once he's activated, and Achane could claim the lead role quickly given Mostert's somewhat lackluster production in recent weeks. Coach Mike McDaniel confirmed Monday that Achane's injury was a sprain and not a tear, per Marcel Louis-Jacques of ESPN.com, which could make it easier for him to immediately resume handling his normal workload, rather than having to ramp things up slowly.
