It's not a pretty picture for RJ. While Darren McFadden is out for the game, the matchup is a terrible one. Jennings has also had an injury-prone label since he tore his ACL two seasons ago. That said, he should still resume much of the role as Oakland's primary runner.
The Chiefs have completely turned around their D and Jennings will see some tough sledding on Sunday. Although, the Chiefs are 30th in yards-per-carry allowed this season, they'll stack the box against the terrible OAK passing attack.
Fantasy impact: It's never easy to play a backup and it's even harder when he's not at 100 percent. Jennings is a tough guy to play this week and the Raiders have really struggled to move the ball. He's a desperation flex on most leagues and his value has a short shelf life since Darren McFadden shouldn't be out for too much longer.
