Dolphins' Jay Ajayi: Fills in for Foster

With Arian Foster inactive, Ajayi will start at running back for the Dolphins on Sunday against the Titans.

Analysis:

Opportunity thus knocks in Week 5 for Ajayi, especially if he gets off to a solid start out of the gate Sunday. Coach Adam Gase noted earlier this week that he was planning on whittling down the Dolphins' running back rotation this week, after using a committee of Ajayi, Damien Williams, Kenyan Drake and Isaiah Pead over the past two games.
