The Houston Texans will start Case Keenum at quarterback on Sunday when they visit the Kansas City Chiefs.

Matt Schaub has been struggling this season, but has been ruled out due to an ankle and foot injury.

"We're struggling, and we're looking for a spark," Gary Kubiak said. "I think he deserves an opportunity to go out there. It's a tough place to play. It's a tough place to get your first start and all that good stuff. But I'm not sending him out there by himself. I'm sending him out there with his football team, and the guys understand that."

T.J. Yates had been the No. 2 quarterback on the depth chart.
