HOUSTON (AP) -- Arian Foster led the NFL in rushing last season, and Texans teammate Steve Slaton was the top rookie rusher in 2008.
Throw in Ben Tate, Derrick Ward and Chris Ogbonnaya, and a team that once struggled to find a dependable running back is now overstocked.
Foster was on Houston's practice squad for much of 2009 before last year's breakout season, when he rushed for 1,616 yards and 16 touchdowns.
He sat out much of Friday's practice after experiencing tightness in his hamstring, but should be OK. It was a setback that coach Gary Kubiak says highlights the need to have many options at the position as players get banged up throughout the season.
