Raheem Mostert of the Miami Dolphins did not practice on Thursday due to knee and ankle issues. However, the team listed it as 'veteran rest' on the injury report, indicating that he is not in danger of missing Sunday's game against the Cowboys. Mostert has been the lead runner for the Dolphins in recent weeks, but his workload has been managed carefully. If the Dolphins fall behind in the game, rookie De'Von Achane may see more playing time in passing situations.
