McCaffrey (hamstring) isn't participating at the start of Friday's practice and thus appears unlikely to play in Sunday's game against the Vikings, David Newton of ESPN.com reports.
He was a limited participant all last week and again this Wednesday, before downgrading to DNP on Thursday and possibly now Friday. It points to a likely third straight absence for the star running back, though coach Matt Rhule said Wednesday that McCaffrey appeared 50/50 for a return this week. Joe Person of The Athletic did see McCaffrey getting off a golf cart and heading to an indoor field, which suggests he's at least doing some form of stretching/conditioning/running. If he misses another game, Chuba Hubbard again will fill in as the lead runner.
