After a humiliating defeat a week before against the Dolphins, the Texans' defense looked much better holding the Titans to just a field goal in the 1st quarter. Houston's offense scored a touchdown early in the 2nd quarter to take a 7-3 lead. On the ensuing kickoff, Tennessee's Bishop Sankey fumbled the ball with Kurtis Drummond recovering it for Houston. The Texans settled for 3 off the turnover with a 38-yard field goal from Nick Novak. Late in the 3rd quarter Brian Hoyer connected with former Titan Nate Washington for a 42-yard touchdown pass, extending the Texans' lead to 17-6 with Novak making the PAT. To start out the 4th quarter, Kevin Johnson got his first career interception by picking off a Zach Mettenberger pass. Houston failed to capitalized on the turnover, however Tennessee turned the ball over after a J. J. Watt sack, giving the Texans the ball at the Titans' 10-yard line. The Texans scored another 3 points off of the turnover, with Novak making a 24-yard field goal. Houston defeated Tennessee 20-6 and improved to 3-5. Watt, Whitney Mercilus and Jared Crick combined for a total of 6 sacks for the Texans' defense.
