Harris leads the group with 691 racing yards on 137 efforts, with two touchdowns.
He had hurt his spine at the fourth quarter of a Week 14 loss to the Los Angeles Rams, but finally was deemed healthy before this week and was not on the injury report Wednesday after the Patriots held his first clinic to get ready for the Dolphins.
Harris, however, was added to the accident report another day due to his ankle, opening the door for former No. 1 rear Sony Michel to reunite to the top place.
Patriots running backs coach Ivan Fears stated on Dec. 11 that Michel will be prepared if the chance presented itself.
“He is a true team player. He understands Damien is playing well, and Sony is kind of waiting to get a chance to demonstrate what he could do,” Sony said at the moment. “He constantly practices hard and can be the type of man you love having about and may rely on. I am quite blessed. Regardless of who goes, I know I have good players who will step in and keep us on course “
The Patriots (6-7) are clinging to long-shot playoff hopes, together with ESPN’s Football Power Index providing them a 3 percent chance to adapt.
They’ll have to win their remaining three matches — in Miami, then at home from the AFC East-leading Buffalo Bills and the winless New York Jets — to give themselves an opportunity.
