Harris reverted back to the Patriots' practice squad Friday.
Harris was elevated to the team's active roster ahead of Thursday's 21-18 win over the Steelers but didn't see any snaps in the contest. With Ty Montgomery having been waived by New England on Friday, Harris could be elevated once again ahead of the Patriots' Week 15 game against the Chiefs to provide depth in a backfield that also includes Rhamondre Stevenson (ankle), Ezekiel Elliott and JaMycal Hasty.
