The 2011 Houston Texans season was the franchise's 10th season in the National Football League (NFL) and the 6th under head coach Gary Kubiak. The Texans improved on their record from the 2010 season, despite losing starting quarterback Matt Schaub & backup Matt Leinart to season ending injuries. Third stringer T.J. Yates filled in, and earned the franchise's first playoff berth by defeating the Cincinnati Bengals 20–19 in Week 14 and clinching the AFC South. It also assured the Texans of at least one playoff game at home—the first NFL playoff game in Houston since 1993. After reaching the Divisional match against the Baltimore Ravens, the Texans suffered their maiden loss in the NFL Playoffs, losing 20–13.

Prior to the season, former Cowboys head coach Wade Phillips was hired as defensive coordinator, replacing Frank Bush, who was fired.[1] The Texans defense made major improvements in Phillips' first year calling Houston's defensive plays. The team allowed the fourth-fewest points in the league in 2011 (compared to fourth most in 2010), the second-fewest yards allowed (third-most in 2010) and third-fewest yards per play (4.8, compared to 6.0, second-worst in 2010). Not only do the 2011 Texans hold the record for least points conceded in the average game of a season for the team with 17.4 points, which happened nine times, but they also got a +103 point differential, which is the best in franchise history. Of the Texans' 10 wins, 9 of them were decided by at least 6 points.

T. J. Yates left the game after the Texans' first offensive drive with a bruised left shoulder. He was replaced by Jake Delhomme for the rest of the game. Houston scored a touchdown with 0:14 left to trail 22–23. To avoid overtime and further injuries, head coach Gary Kubiak decided to try a two-point conversion. Tight end Joel Dreessen was flagged for a false start, moving the Texans back 5 yards. The attempt would ultimately fail as backup center Thomas Austin snapped the ball over Delhomme. Neil Rackers would attempt an onside kick, but it was recovered by Lavelle Hawkins for the Titans, securing a win for Tennessee. With the loss, the Texans would end their season at 10–6 and the AFC's #3 seed.

Making their NFL postseason debut as the AFC's #3 seed, the Texans began their playoff run at home in the AFC Wild Card Round against the #6 Cincinnati Bengals, in a rematch of their Week 14 contest. Not only was this the Texans' first postseason game, it was the franchise's first game ever broadcast nationally on NBC, they were also the last NFL team to finally play on NBC, since their 2002 inception.
Houston trailed in the first quarter with Bengals running back Cedric Benson getting a 1-yard touchdown run, yet the Texans answered with an 8-yard touchdown run from running back Arian Foster. Cincinnati struck back in the second quarter with kicker Mike Nugent getting a 37-yard field goal, but Houston took the lead with a 39-yard field goal from kicker Neil Rackers, followed by rookie defensive end J.J. Watt returning an interception 29 yards for a touchdown. From there, the Texans took control with rookie quarterback T.J. Yates finding wide receiver Andre Johnson on a 40-yard touchdown in the third quarter, followed by a 42-yard touchdown run by Foster in the fourth quarter.
With the win, the Texans improved their overall record to 11–6.
