HOUSTON (CBS HOUSTON) – The Houston Texans dropped their season opener for the first time in six years 27-20 to the Kansas City Chiefs on Sunday. The Texans offense had problems stopping the Chiefs defensive pressure allowing four sacks, one with a fumble and the defense had trouble stopping tight end Travis Kelce, who scored twice for Kansas City in a game whose score was tighter than the game.

Head coach Bill O’Brien might have added some excitement to the team’s practice this week when he replaced starting quarterback Brian Hoyer with backup Ryan Mallett late in the fourth quarter. Mallett led the Texans on touchdown drive and a field goal to bring the game within one score for the home team, but a failed onside kick ended the second-year Texans dream of a historic comeback.

Mallett finished the game 8/13 for 93 yards and one touchdown while starter Brian Hoyer finished 18/34 for 236 yards and one touchdown, one interception and a fumble lost. The Texans missed starting running back Arian Foster, combining for just 98-yards on 21 total carries between all ball carriers.

The Texans defense started the game by forcing a Kansas City punt leading to the first regular season snaps of Brian Hoyer’s Texans career.

Chiefs rookie cornerback Marcus Peters intercepted Hoyer’s first pass allowing Kansas City to take over in the Texans red zone. Soon after Travis Kelce would catch a strike from Alex Smith to give the Chiefs a 7-0 lead early.

The Texans would fail to move the ball effectively allowing the Chiefs to take over. This drive would also end with Smith hitting Kelce, this time for a 42-yard score. The Texans would trail 14-0 as Brian Hoyer would take over late in the first.

Hoyer would find open receivers for big chunks, completing all five of his passes. The final Hoyer pass found DeAndre Hopkins in the corner of the end zone for the team’s first touchdown of the season. Randy Bullock would miss the extra point making it 14-6 Chiefs.

The Chiefs would answer with a field goal while the Texans would punt giving way to another Chiefs field goal making it 20-6.

Disaster would strike for the Texans on the next drive as Hoyer fumbled allowing the Chiefs to take over on the Texans’ seven. Jamaal Charles would catch a touchdown from Alex Smith on the next play to give the Chiefs a dominating 27-6 lead.

A Texans punted on their ensuing drive and finally forced a Chiefs punt. With just over two minutes left in the half, the Texans would take over on their own 20. A few nice completions from Hoyer had the Texans quickly in the red zone. A sack setup a third and nine with 20 seconds left in the half. A pass deflection led to a 34-yard Randy Bullock field goal.

The Texans trailed 27-9 at halftime. Bill O’Brien told Texans Radio on SportsRadio 610 he thought the final third down play was a pass interference that the referees didn’t call.

The Texans would open the second half with a punt and then force the Chiefs to punt as well when Jadeveon Clowney chased down and pushed Jamaal Charles out of bounds short of a first.

The Texans offense would fail to get a first down leading to a punt. Bill O’Brien would win his first challenge of the season on the drive by the Chiefs as he was able to get a long completion on the sideline overturned. A Kareem Jackson penalty would keep the Chiefs drive alive allowing them to convert a third and one. The Texans would hold on the new set of downs to force a punt.

The Texans next drive quickly made it deep into the Chiefs territory thanks to a 32-yard reception by Nate Washington. A third and one play saw DeAndre Hopkins drop a pass and the following fourth and one play Alfred Blue was stuffed short.

A J.J. Watt one-armed sack would end the Chiefs ensuing drive early.

Ryan Mallett would take over near the six-minute mark. He would complete a few passes to DeAndre Hopkins and then the Texans would enter the red zone thanks to a penalty. He would then hook-up again with Hopkins in the corner of the end zone for a touchdown. The Texans would complete the two-point conversion with another Hopkins-Mallett connection.

The Chiefs would force the Texans to burn all their timeouts before punting the ball. The Texans would take over on their own 22 yard-line with 2:47 left in the game.

A sack on first down was quickly erased by a Mallett strike to Keith Mumphery. Ryan Mallett rushed for a first down to take the team into the two-minute warning. Two big competitions in a row had the Texans on the 30 with 1:40 left. Three incompletions gave way to a Texans field goal attempt. Randy Bullock made the 47-yard try to cut the Chiefs lead to 27-20 with just over one minute remaining. A failed onside kick sealed the game for the Chiefs.

Texans 2014 first overall pick Jadeveon Clowney saw significant playing time for the first time since last year’s opener against the Washington Redskins. Clowney made 3.5 tackles on the day but made multiple disruptions to the Chiefs offense. Linemate J.J. Watt led the team with nine tackles and two sacks on the day for a defense that didn’t allow any second half points.

The Texans will travel to Carolina to face the Panthers next Sunday while the Chiefs host the Denver Broncos on Thursday Night Football on CBS in week 2.
