The on-again, off-again season of Houston Texans running back Arian Foster is back on.

According to the Texans' Twitter site, Foster is ready to go this weekend when the Texans play the Pittsburgh Steelers.

Foster missed the season opener against Indianapolis, played against Miami in week two before reinjuring the hamstring, and then sitting out last week against the New Orleans Saints.

In the meantime, the Texans have been riding backup running back Ben Tate, who had 100 yards rushing in each of his first two games.
