Kubiak said Monday that he will prepare T.J. Yates and Case Keenum to start this Sunday against the undefeated Kansas City Chiefs, who arguably boast the best defense in the NFL. Schaub's status will be determined at the end of the week, according to Kubiak.
Schaub was "very sore and beat up" Monday with foot/ankle injuries. Yates is the logical candidate to start because he has been the backup all season and replaced an injured Schaub in Houston's 38-13 loss to the St. Louis Rams on Sunday. Then again, Yates threw two interceptions in a brief appearance.
Keenum pushed Yates for the Texans' backup job in training camp, but it would be a surprise if Kubiak asked the second-year player to start. Yates doesn't have a ton of experience, but seven starts (including two in the playoffs) is better than nothing.
It's very possible that Kubiak just included Keenum's name because coaches hate revealing any information until they absolutely have to. Yates clearly was ahead of Keenum last week.
