Houston started the season going into their bye week at 3–5, including blowout losses to the Atlanta Falcons (21–48) and against the Miami Dolphins (26–44). However, the Texans had a surge in the second half of the season, going 6–2 after the bye. The 2015 season marked the first time the Texans beat the Colts in Indianapolis, helped in part by third–string quarterback Brandon Weeden. The Texans matched their win total from the 2014 season, finishing 9–7, and gained their first division title and postseason trip since 2012, but were shut out, 0–30, at home by the Kansas City Chiefs in the Wild Card round.
In the 2015 season opener, the Houston Texans took on the Kansas City Chiefs with Brian Hoyer in his first regular season start as the Texans' quarterback. Hoyer's first pass was intercepted which eventually led to a Kansas City touchdown. The Chiefs managed to score another 7 points off of turnovers to take a 14-0 lead with 4:28 left in the first.

Nonetheless the Texans couldn't manage a comeback and fell to the Chiefs 27-20.
This is the first time since 2009 where the Texans lost their season opener. Houston kicker Randy Bullock became the first player to miss a point-after attempt following a rule change for the 2015 season, which requires the ball to be snapped from the 15-yard line.
Ryan Mallett was given the starting quarterback position against the Panthers. The Texans' only lead of the game came in the first quarter following a 43-yard field goal from Randy Bullock. Following 10 unanswered points from Carolina in the 2nd quarter, Houston trailed 3-10 going into halftime. Early in the third quarter Houston tied the game at 10 a piece. A Carolina touchdown late in the 3rd quarter and another early in the 4th sealed a Panthers victory as the Texans couldn't manage a comeback. With the loss Houston dropped to 0-2, their worst start since the 2008 season.

The kicking problems continued for the Buccaneers after Brindza missed a 41-yard field goal with 7:21 left in the 3rd, then again from 33 yards with 10:56 left to play. Following another missed field goal for Tampa Bay, Houston went 77 yards in just 5 plays to score a touchdown with an Alfred Blue 20 yard rush. With Bullock missing his 2nd extra point attempt of the season, the Texans extended their lead to 16-9 with 9:19 left to play.

Taking the knee on a two-point conversion, the Falcons finished with a 48-21 victory.
