Earl Mitchell, who left Sunday's game with a calf injury, missed another day of practice on Friday. He has not practiced all week and his status for Sunday's game against the Baltimore Ravens is uncertain.
If Mitchell cannot play, much of the playing time will go to rookie Jordan Phillips. The Dolphins also added Robert Thomas from the New England practice squad this week.
The Dolphins are having some issues at wide receiver.
Rishard Matthews, who suffered a rib fracture in the loss to New York, is not playing against Baltimore. And Kenny Still apparently injured his ankle in practice on Thursday and did not practice Friday.
