Following the Raiders bye week, the team traveled to Mexico City to play the Houston Texans in a home game. A win for the Raiders would put them in sole possession of first place in the AFC West after a loss by the Kansas City Chiefs the day before. However, the Raiders defense struggled early and were unable to put much pressure on Texans' quarterback Brock Osweiler. However, they were helped all night by controversial calls by the officiating crew. The first was in the Texans' first drive as DeAndre Hopkins appeared to have stayed in bounds and scored on a 60-yard pass from Osweiler. However, officials ruled that Hopkins had stepped out of bounds and the play was blown dead. As a result, the play could not be reviewed and the Raiders only surrendered a field goal on the opening drive of the game. Following consecutive four-and-outs by both teams, the Raiders offense mustered a drive into Houston territory capped off by a 17-yard touchdown pass by Derek Carr to Jalen Richard to give the Raiders a 7-3 lead to begin the second quarter. On the ensuing kickoff, the Texans turned the ball right back over to the Raiders, but the offense could not punch the ball in from the one-yard line and settled for a Sebastian Janikowski 19-yard field goal to extend the lead to 10-3. The Texans quickly answered as Osweiler hit Braxton Miller for a 12-yard touchdown pass to even the score at 10-10. Neither offense was able to manage much for the remainder of the half and a sack by Khalil Mack ended the first half with a tie score. On the first play of the second half, Carr was pressured and threw a deep pass that was intercepted by the Texans. The ensuing 13-play drive capped off by a one-yard touchdown run Lamar Miller gave the Texans the lead, 17-10. The Raiders responded, getting to the Texans two-yard line, but could not punch the ball in again and settled for a second Janikowski field goal cutting the lead to 17-13. The Texans ended a long drive with a Nick Novak field goal to extend the lead to 20-13 with 11 minutes remaining in the game. Carr responded by finding Jamize Olawale wide open for a 75-yard pass and run to tie the game at 20. The Texans pushed the ball deep into Raiders territory again but were stopped on short yardage situations twice as controversial spots of the ball by officials turned the ball over to the Raiders on downs. The Raiders took advantage as Carr hit Amari Cooper on a pass and catch for a 35-yard touchdown play. The extra point gave the Raiders a 27-20 lead with 4:43 remaining in the game. The defense who had mustered little pressure on Osweiler all night, allowed a first down by the Texans, but then forced a punt with 3:13 remaining. On second and seven from their own 23-yard line, Carr heaved a 29-yard pass to Richard for a first down. After the two minute warning and the Texans final timeout, Latavius Murray was able to get another first down and the Raiders were able to run out the clock. The win put the Raiders at 8-2 on the season and gave them the No. 1 seed in the playoffs at the time. Carr finished with 295 yards and three touchdowns while the Raider running game only mustered 30 yards rushing against the Texans defense. The Raiders also clinched a non losing season for the first time since 2011. Another win will clinch the Raiders their first winning season for the first time since 2002.
