Arian Foster returned for one padded practice on Wednesday. The Houston Texans had Thursday off and now he's back to watching from the sideline.

"You know, he’s doing OK," Texans coach Bill O'Brien said. "It’s kind of a day-to-day thing. It’s nothing serious. I would assume, guess you can’t assume anything, but I would assume he would be back pretty soon."

Foster played in eight games last season, then went on injured reserve and had back surgery. He also suffered calf and hamstring injuries during the offseason, which might have been related to his back issue. Foster turns 28 in August and has had more than 1,000 carries in the past three and a half seasons.
