Najee Harris and Jaylen Warren to split carries?

NFL Network's Ian Rapoport says Steelers RBs Jaylen Warren and Najee Harris "could split carries" vs. the 49ers today. "Najee Harris is going to be the starter, getting the first- and second-down snaps. Jaylen Warren third-down snaps," Rapoport adds. "But Warren is expected to get a little more of the first- and second-down snaps than usual." We've heard conflicting reports on this backfield all summer, so it'll be nice to actually get a look at it today. We'd still try to keep Warren on fantasy benches; Harris is a low-end RB2 in a tough matchup vs. San Francisco.
