Passage: The Texans received the ball first and started at their 20 following a touchback. Fitzpatrick connected to Foster for 41 yards for a touchdown. Following the official review, Foster was ruled out at the Oakland 1. On the following play Fitzpatrick connected with Watt (who was in as a tight end) for a touchdown, with Bullock's extra point good. The Texans scored first and lead the Raiders 7-0 with 9:41 left in the first. After the Raiders received the ball they were forced into a 3 and out, punting the ball back to Houston. The Texans managed to score on their next possession, eating up much of the clock in the process. With 0:05 left in the 1st, Houston lead Oakland 14-0. The Raiders started the 2nd quarter with the ball following Houston's score late in the 1st. Oakland managed to get down to the Houston 31 before Carr's pass was intercepted by Jackson, who returned it for 65 yards to the Oakland 24. After an offensive holding penalty, the Texans were forced into a 2nd and 19, running for 4 yards for a 3rd and 15, before Fitzpatrick's pass fell short to Foster. On 4th and 15, Bullock kicked a 33-yard field goal to give the Texans a 17-0 lead with 10:34 left in the 2nd. The rest of the half went by quietly, with both teams failing to convert a 1st down. At the half, Houston was up 17-0. Oakland received the ball to start the 2nd half, managing to get down to the Houston 38. Swearinger fumbled the ball (twice) before it was picked up by Joseph and returned for 49 yards to the Oakland 21. The Texans again capitalized on the turnover, this time getting a touchdown following a Fitzpatrick pass to Hopkins. Houston lead 24-0 with 8:34 left in the 3rd. After Oakland received the ball back they were hit with a 10-yard penalty, forcing a 2nd and 20. Oakland failed to get over the penalty, punting the ball on 4th and 14. Houston scored on yet another possession, with a 39-yard Bullock field goal, giving the Texans a 27-0 lead. After the Raiders got the ball back, the marched down the field to the Houston 39, before the end of the 3rd. With Oakland still yet to score, Houston lead 27-0. Oakland's drive stayed alive after they converted on a 4th and 1. Another "saving grace" came after a defensive holding penalty for 10 yards gave the Raiders a 1st down. McFadden's 1 yard run finally put Oakland on the board, trailing 7-27 with 14:07 left to play. The Raiders kicked the ball back to the Texans, who ate up as much clock as possible with numerous running plays. Houston ended their drive with a 46-yard field goal from Bullock, giving them a 30-7 lead. On Oakland's next possession, Carr's pass was intercepted by Reed at the Oakland 15 and ran it to the 11. Going into a 4th and 8, Bullock attempted a 27-yard field goal, but it was blocked. Following the blocked kick, the Raiders started at their 17 before getting another touchdown to trail 14-30 with 0:14 left. Oakland attempted an onside kick, but went out of bounds, but two offsetting penalties gave the Raiders another chance. On the second attempt, the Texans recovered the ball to win the game 30-14. With the win, the Texans started a season 2-0 for the fifth year in a row and matched their win total from the 2013 season. This was the only game of the 2014 season where the Texans scored in the 1st quarter until week 7 against the Steelers.
