According to Dolphins HC Adam Gase, the running back now has a clean slate entering Week 2.
“We’re back to basically [where] he’s back in meetings, he’s back in the building,” Gase said. “We left him back. That was my decision and we’ve cleaned that up. We’ll move past that and basically this is a new day for him today.”
Ajayi fumbled and dropped a ball in limited time in preseason Week 4, which was part of the reason he entered Gase's doghouse. Ajayi could still end up with a role in the offense but right now it seems pretty clear it belongs to Arian Foster.
