After yet another loss, the Houston Texans are trying to figure out how to correct their mistakes and deal with several more injuries after already losing stars J.J. Watt and Deshaun Watson for the season. Houston's 24-13 defeat at Tennessee on Sunday was its fifth loss in six games to drop the team to 4-8. Already decimated by injuries, the Texans sustained several more against the Titans, leaving them thin at several positions heading into Sunday's game against the 49ers. Tight end C.J. Fiedorowicz, receiver Braxton Miller and running back Alfred Blue all suffered concussions against the Titans.

Scarlett had been playing in place of Whitney Mercilus, who tore his pectoral muscle on Oct. 8 in the same game where Watt broke his leg. Now the Texans will likely have to start Gimel President at the position. President was signed as an undrafted free agent and has spent most of this season on the practice squad. Despite the mounting injuries and the team's poor record, O'Brien isn't planning to use the remaining games to look to the future or evaluate younger players. "The big thing is winning," he said. "I think within winning you may, within the goal of winning, you may be able to do certain things, but at the end of the day, if it doesn't point toward winning, you're not doing it." On top of the injuries on Sunday, the Texans struggled with several uncharacteristic miscues. Jeff Allen, who had been the team's right guard for most of the season, moved to left tackle against the Titans, and committed three straight false start penalties in the fourth
