Arian Foster has become one of the NFL's best running backs again after an injury-plagued 2013.

Foster rushed for at least 100 yards in the Texans' past three games. Foster has averaged 122.7 yards, including 12 runs of at least 10 yards and 5.8 yards a carry in the past three games.

Foster, who missed more than half of last season because of injuries and underwent back surgery in the offseason, had 542 yards rushing in 2013. 

J.J. Watt has been named the AFC's Defensive Player of the Month for September, while Philip Rivers received offensive honors.

According to Pro Football Focus, Watt has 32 quarterback pressures this season. That number would have put Watt in Top 20 among 3-4 defensive ends for the entire 2013 season.

Rivers has completed 70.1 percent of his passes and posts a 114.5 passer rating.
