Dolphins rookie running back Jay Ajayi has been placed on the reserve injured-designated for return list because of a chest injury, meaning he'll be eligible to play after the eighth week of the season.
Ajayi should be healthy enough to return by then, general manager Dennis Hickey said Sunday.
Fantasy Impact:
Damien Williams had a good camp and will backup Lamar Miller. LaMichael James also showed flashes at time and will be listed as the team's RB3.
