Harris (hamstring) was estimated as a limited participant on Tuesday's practice report.
Harris picked up a hamstring injury during a Week 13 win in Buffalo, which subsequently kept him on the sideline in the Patriots' next game. While his practice reps have been capped in the meantime, he proceeded to suit up in Weeks 16-18, taking 38 carries for 175 yards and six touchdowns to go with five catches on six targets for 48 yards. During that same stretch, Rhamondre Stevenson notched 24 touches in two appearances, while Brandon Bolden had 16 touches in three. The Patriots haven't been shy about involving each of the trio from game to game, but assuming Harris is active for Saturday's wild-card contest against the Bills, he should be the lead runner yet again.
