Joining Drake (hamstring) and Jay Ajayi in the Miami backfield is veteran Arian Foster (Achilles), who signed with the team Monday, the Palm Beach Post reports.
Drake, who the report describes as "a talented pass-catcher but unproven downhill runner," now faces added competition for touches in the Miami offense, with his fantasy upside taking a hit due to the fact that a (presumably) healthy Foster is a candidate to earn a good chunk of both carries and catches in the Dolphins' 2016 backfield.
