Matt Schaub was still feeling the effects Wednesday of a concussion from a helmet-to-helmet hit against San Diego, and coach Gary Kubiak said he probably wouldn't play Sunday against Oakland. "It's feeling better, clearing up a little bit," he said. "Headaches are subsiding, so we'll take it day to day." With Schaub likely out, Sage Rosenfels should get the third start of his career and his first since a 22-0 loss to Cleveland in 2005 when he was with Miami.

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."

Quarterback Matt Schaub pronounced himself "definitely" ready to play against the San Diego Chargers on Sunday despite back, hip and ankle problem but conceded the decision as to whether he or backup Sage Rosenfels starts remains coach Gary Kubiak's to make. "It feels better than it did Thursday," said Schaub, who was twice knocked out of the Tennessee game last Sunday. "It's all getting better every day. I got a lot of reps (Friday), but it's still a game-time decision. As a player, I've just got to get myself ready. We'll see. I've never been through a situation like this. I don't know if the process will work. It's something we'll have to work out as a football team."

The Texans downplayed Sunday's injuries to quarterback Matt Schaub, who left the game against the Titans after two hard hits. Schaub hurt his ankle when he was sacked in the first quarter by cornerback Cortland Finnegan. Schaub returned in the second quarter only to be sidelined permanently by Albert Haynesworth after injuring his hip and lower back. The X-rays on his leg came back negative. MRIs were scheduled for Sunday evening. "I'll tell you what: Matt is just beat up," Texans' coach Gary Kubiak said. "He's having an MRI. We're concerned about his hip. But just in general, Matt's beat up."

Houston Texans' quarterback Matt Schaub left Sunday's 38-36 loss against Tennessee for the second time after a helmet-to-helmet hit by Albert Haynesworth in the second quarter. The Texans trailed 19-7 with a minute left in the first half when Haynesworth delivered the blow on Schaub, who threw incomplete. Haynesworth was whistled for a personal foul. Schaub lay on the field for several minutes before gingerly jogging off. Team officials said Schaub injured his right hip, and he did not return.

Rob Bironas kicked an NFL-record eight field goals, and the Titans needed every one of them to hold off the Texans on Sunday. Bironas' 29-yard field goal as time expired led the Titans to a 38-36 win.

Three hours after being an unwitting participant in a collision that resulted in a concussion, an unsightly taunting episode, and ample vitriol emanating from the visitors' locker room, Texans defensive tackle Travis Johnson was still seething. The elapsed time hadn't soothed Johnson's angst. He was unapologetic in his vulgar impressions of Miami Dolphins quarterback Trent Green, who lost consciousness when his helmet collided with Johnson's knee during a botched running play in the first quarter of the Texans' 22-19 victory on Sunday. Even after witnessing a motionless Green immobilized and transported to Methodist Hospital (Green returned to Reliant Stadium prior to the Dolphins' departure), Johnson was unabashedly furious afterward. "At 12:01, I had a lot of respect for Trent Green. At about 12:20, I said, '(Forget) Trent Green,' because the bottom line is it was a malicious hit," Johnson said. "It was uncalled for. He's like the scarecrow. He wanted to get courage while I wasn't looking and hit me in my knee instead of trying to hit me in my head." Given additional time to calm down, Johnson ? at the urging of Texans officials ? readdressed the incident and his reaction. Roughly 20 minutes after his initial tirade, Johnson showed contrition for his behavior and remorse for the fallout from his actions. "I apologize for going off like that," Johnson said. "As a D-lineman, when you have people going at your knees, it's tough on you mentally. But at the same time, I shouldn't have reacted like that. I'm sorry the penalty ended up leading to a score. ''I ended up hurting my team," Johnson said. ''I shouldn't have let my anger get to me. I apologized to coach Kub because I hurt my team. I should have kept my cool. But being in that situation, this is a game of controlled violence. Really, I let my anger get the best of me."

Kris Brown's career day was enough for the Houston Texans to slip past the hapless Miami Dolphins. Brown kicked five field goals, including the winner on a career-long 57-yarder with a second remaining, to lead the Texans to a 22-19 victory over the Dolphins (0-5), losers of eight straight. Brown tied an NFL single-game record with three makes over 50 yards. He hit two 54-yarders earlier in the game. With less than two minutes to go, the Dolphins lined up for what would have been a 56-yard field goal attempt, but instead called a timeout and punted.

The Texans finally have pinpointed what is wrong with Jerome Mathis' left leg, and it's enough to likely sideline him for the rest of the season. After almost two days of testing, team doctors found a "hot spot" in the lower part of his leg, which is causing excruciating pain for Mathis during and after running. The Texans are expected to place Mathis, 24, on injured reserve and sign wide receiver Harry Williams off the practice squad for the game against Miami on Sunday at Reliant Stadium. "He has a stress-related issue in his lower leg," coach Gary Kubiak said Friday. "Our issue right now is trying to make a decision of how long it's going to be before he can get back on the field."
