ESPN and NFL Network report that Dolphins RB Raheem Mostert (knee, ankle) will NOT play vs. the Ravens today. Mostert has been battling various injuries throughout the season, but this will be the first game that he misses. His absence will leave Miami's backfield to De'Von Achane, Jeff Wilson, and Chris Brooks. Achane is likely to get more work with Mostert out, although we doubt Miami makes him a workhorse. Wilson figures to mix in plenty and could be a RB3 or flex option for fantasy teams.
