Schaub hurt his left leg in the first quarter, returned after a brief absence and then left the game for good after a vicious hit from Titans defensive end Albert Haynesworth in the second quarter.
"All the tests were negative, all the x-rays were fine," said Texans' head coach Gary Kubiak. "He's really, he's just beat up. He's got an extremely beat up hip, a lower leg, he's got the thigh that he's been nursing for a couple of weeks. So he's just generally beat up but we think he's going to be okay. We will say that he's day-to-day right now and hopefully he's out there Wednesday and can do something, but he's just very beat up right now."
Sage Rosenfels replaced Schaub against the Titans and completed 22-of-35 passes for 290 and four touchdowns with four turnovers (three interceptions and a fumble). Schaub completed 5-of-9 passes for 23 yards.
