Achane (knee) doesn't have an injury designation for Sunday's game at Washington, David Furones of the South Florida Sun Sentinel reports.

EDGE Analysis

The Dolphins made it official a few hours after coach Mike McDaniel announced Achane was ready to return. The rookie had a setback with his knee in his first game back from a stint on injured reserve, but the Dolphins don't seem too worried about a significant aggravation occurring. Achane figures to share backfield work with Raheem Mostert and possibly Jeff Wilson as well.
