Texans quarterback Matt Schaub might not be starting on Sunday against Kansas City but it has nothing to do with his recent struggles. Schaub suffered an ankle injury in Houston's loss to the Rams on Sunday and that injury could keep him from playing against the Chiefs. Schaub was injured near the end of the third quarter against St. Louis an injury that actually elicited cheers from the crowd at Reliant Stadium in Houston. Coach Gary Kubiak said on Monday that starting Schaub in Kansas City will be an 'end of the week decision.' If Schaub can't go that means either T.J. Yates or Case Keenum will get the start and Kubiak didn't say which guy he'd go with "I'll prepare both Case and T.J." Kubiak said. Yates saw some playing time against St. Louis but didn't do much to impress Kubiak. In just over a quarter of action Yates threw two interceptions including a 98-yard pick-six to Rams linebacker Alec Ogletree.
