Raiders running back Rashad Jennings suffered a hamstring injury in the first half, and he wasn't able to finish the game.
Jennings started in place of Darren McFadden.
Marcel Reece rushed seven times for 32 yards once Jennings left the game. Reece could be in line for a big bump in carries if both Jennings and McFadden are out again in Week 6. The Raiders have a tough matchup at KC next week, though.
