Dolphins running back Jonas Gray was moved to Miami's active roster on Wednesday. Gray had spent the first portion of the season on the practice squad, but the recent injury concerns to Lamar Miller (ankle) and the loss of Jay Ajayi (ribs) require added depth at the running back position.

Even though Gray performed admirably for the Patriots in spurt roles last season, he could have trouble seeing the field in Miami with Damien Williams and Raheem Mostert still in line for the majority of snaps.
