HOUSTON -- Texans running back Arian Foster, who was limited in practice last week with a hamstring injury, is active against the Buffalo Bills on Sunday.
Foster's workload will depend on how his hamstring holds up, a source said.
Foster did not play last weekend against the New York Giants after being limited in practice all week.
Foster rushed 55 times for 241 yards in the first two weeks of the season. The Texans won both games, against Washington and Oakland.
In his absence against the Giants, rookie sixth-round pick Alfred Blue started at running back. He gained 78 yards on 13 carries.
