Mostert (knee) said Monday that he's "way ahead of schedule" in the rehab process after October surgery, David Furones of the South Florida Sun Sentinel reports.
The surgery addressed chipped cartilage in his left knee, and Mostert now has played only nine games over the past two seasons. The Dolphins do expect him to be healthy before Week 1, with Mostert joining the team on a one-year contract shortly after fellow running back Chase Edmonds got a two-year deal. Mostert has the benefit of familiarity with new Dolphins coach Mike McDaniel, formerly the 49ers' offensive coordinator, but Edmonds still is the better bet to lead Miami's backfield in touches. The team also has 2021 holdovers Myles Gaskin, Salvon Ahmed and Patrick Laird on the offseason roster.
