The Miami Dolphins reshuffled their backfield on Monday, and part of the personnel shift at the position included waiving running back Jonas Gray.
Miami announced its moves to release Gray and LaMike James through its official Twitter account. NFL agent Brett Tessler said his client, RB and return man Raheem Mostert, was signed by Miami off the Philadelphia Eagles' practice squad.
Ben Volin of the Boston Globe weighed in on Gray's setback after he was promoted to the Dolphins' active roster just prior to Week 1 and had joined the practice squad only this past Tuesday:
#Dolphins released RB Jonas Gray today.
