Houston Texans star running back Arian Foster returned to practice Thursday, but it was just for one day.

Foster was out Friday with an apparent hamstring injury.

“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 — [but] guess you can’t assume anything — he’d be back pretty soon.”

Foster was joined on the sidelines by wide receiver Andre Johnson, who also has a hamstring injury.
