The Dolphins entered their first game of the season with a 0-0 record, traveling to face the 0-0 Houston Texans. The game was the first start for rookie quarterback Ryan Tannehill and head coach Joe Philbin. Tannehill became the first Dolphins rookie quarterback to start the first game of the season. Entering the game the Texans are the only team the Dolphins have not beaten, holding a 0-6 record all-time against the team. Both teams moved the ball well on their opening drives, but failed to score. The Dolphins received the ball on their own 42-yard line after a missed field goal by Houston kicker Shayne Graham. After a Reggie Bush recovered fumble on 3rd down on the Houston 14-yard line the Dolphins kicker Dan Carpenter attempted and successfully executed a 39-yard field goal with (3:19) left in the first quarter. Both defenses held steady, keeping both offenses out of the redzone heading to the mid-way point of the second quarter. However, at the (7:35) point, quarterback Tannehill was intercepted by Johnathan Joseph at the 50-yard line for 36 yards. Within the shadow of their own goal posts the Dolphins held the Texans to a Shayne Graham 35-yard field goal. The interception by Tannehill was the first of his career, and marked a downhill spiral for the rest of the game. Following the score the Dolphins moved quickly to the Houston side of the field after a 10-yard rush by Reggie Bush and 32-yard pass to running back Daniel Thomas. But after a few incomplete passes, Tannehill had his pass intended for receiver Legadu Naanee deflected by a defensive lineman and intercepted by linebacker Brian Cushing with (4:06) left in the second quarter. The Texans quickly turned the turnover into points, with an Arian Foster 14-yard rush. On the first play following the Houston kickoff quarterback Tannehill again had his pass deflected by a defensive lineman, but instead was intercepted by Kareem Jackson. After a defensive pass interference penalty, running back Arian Foster rushed for his second rushing touchdown of the game at the (0:49) mark. Again following the kickoff the Dolphins again turned the ball over following a Daniel Thomas fumble. The turnover was shortly followed by a 14-yard pass touchdown from Houston quarterback Matt Schaub to receiver Andre Johnson at the (0:12) mark. Following a quick three and out by the Texans following halftime, punt returner Marcus Thigpen returned a punt for 72 yards for a touchdown. But for the remainder of the game the Dolphins offense failed to produce any scores, but held the Texans defense to two Shayne Graham field goals: 40 and 19 yards, respectively..
