The status of Houston Texans running back Arian Foster is again in question.

Foster returned to the Texans' lineup Sunday after sitting out Week 1 due to a left hamstring injury. But the NFL's leading rusher last season left Houston's 23-13 win over Miami after only 10 carries when he re-aggravated the hamstring.

Foster didn't jog with his teammates on Monday and head coach Gary Kubiak said the team will evaluate his status Wednesday.

"He (Foster) is a little sore today," Kubiak told the FoxSportsHouston.com on Monday. " ... I think it is a going to be a process with Arian working himself back to full speed and carrying the full load. I think (Sunday) was a step in the process and we'll see where we're at Wednesday."

Ben Tate, seeing his first action since Houston drafted him in 2010, has been a key reason why the Texans are 2-0 without their star running back. The former Auburn Tiger topped 100 yards in both games in Foster's place.

"He's playing really well," Kubiak said. "As we work Arian back into what we're doing, and get him back to full speed, Ben's going to probably carry most of the load right now. But he's responded very well, he's getting better every time out."

Kubiak also said "there's a good chance" that receiver Kevin Walter (right shoulder bruise) will return for Sunday's game. As with Foster, Walter's replacement proved just as capable. Jacoby Jones caught three passes for 48 yards and had a 40-yard punt return.

"We've had a few issues on offense, with Arian and now with Kevin," Kubiak said. "But we've had some guys step up, so that's very important."
