Foster practices for Texans

HOUSTON, Sept. 28 (UPI) -- Arian Foster, the defending NFL rushing champion who has played in just one of the Houston Texans' three games this season, returned to practice Wednesday.

Foster has been plagued by a hamstring injury this year after gaining a league-high 1,616 yards in 2010.

He missed the opening game of the season, rushed for 33 yards in a 23-13 win over Miami and then did not play last week against New Orleans.

Foster went through all the drills Wednesday in preparation for Houston's hosting of Pittsburgh Sunday. Both teams have a 2-1 record.

Foster is in his third year with Houston, having played his college football at Tennessee. Last year's second-leading rusher, Kansas City's Jamaal Charles, has already been lost for the season.

The leading rusher through three weeks this season is Oakland's Darren McFadden with 393 yards.
