The Houston Texans, whose three straight losses have sent them to the bottom of the AFC South, are also dealing with another unwanted streak. For the second straight week, quarterback Matt Schaub was knocked out of the game because of a helmet-to-helmet hit. The first one caused a bruised hip. This one, by San Diego's Drayton Florence after his second interception, left Schaub dazed and rubbing his head on the sideline. Houston coach Gary Kubiak wouldn't call Schaub's latest knock a concussion, instead dancing around the question when asked what grade of a concussion it was. "No, they really didn't tell me that, just that he got dinged pretty good," Kubiak said Monday. "He's having some headaches."
