Arian Foster (born August 24, 1986), is an American football running back for the Houston Texans. He was signed by the Texans as an undrafted free agent in 2009 and was added to their active roster from the practice squad on November 17, 2009. He played college football at Tennessee.

Foster was born August 24, 1986 in Albuquerque, New Mexico, to Carl Foster, a former wide receiver for the University of New Mexico, and Bernadette Sizemore, an administrative assistant for the university. Foster competed in football at Valley High School, where coaches told him that he was not good enough to play running back. His parents divorced in 2000, and in 2002 he moved to San Diego, California, to be with his father. Foster competed in football at Mission Bay Senior High School, where he initially played as a linebacker, but became a full-time running back in his senior year. He was Mission Bay's featured running back that year, and led San Diego County in all purpose yards with 2,500 while compiling 2,093 rushing yards and 24 touchdowns in addition to six scores on kickoff returns. In a game against Claremont, Foster ran for 321 yards and for his efforts, he was named San Diego Union Tribune All-San Diego Western League Player of the Year, received All-West Region appointment by PrepStar, and also earned All-California Interscholastic Federation honors. Then-Tennessee offensive coordinator Randy Sanders and running backs coach Trooper Taylor were impressed by Foster when recruiting in San Diego. Foster chose to attend Tennessee and was part of the 2004 signing class.
