He's expected to start at running back, and the Vikings will decide how many carries Peterson gets based on how he plays early in the game. Minnesota's Week 15 inactives are S Harrison Smith, WR Laquon Treadwell, DL Stephen Weatherly, OG Willie Beavers, OG Brandon Fusco, CB Trae Waynes, and QB Taylor Heinecke.

While it’s tempting to roster Peterson in a favorable matchup, it’s best to fade him. When healthy, he averaged 1.6 yards per carry on 31 attempts, and Football Outsiders ranks Minnesota’s offensive line dead last in adjusted line yards per carry (3.23). It’s hard to predict how much he’ll actually play given his injury, especially when the team is basing it on how he feels; it could go in several different directions. With Matt Asiata active, he’ll have to worry about his touchdowns getting vultured. There is too much going against Peterson so make him a viable fantasy option.
