HOUSTON -- Houston running back Arian Foster will miss Sunday's game against Arizona with an injured back.
The Pro Bowler didn't practice all week after injuring his back on Houston's first series against Indianapolis last week. He also missed most of Houston's previous game with a hamstring problem.
The team hasn't disclosed exactly what's wrong with Foster's back. Interim coach Wade Phillips said Friday that Foster had visited specialists about the problem and will likely seek more opinions.
Ben Tate, who is still recovering from four broken ribs, is expected to start in his place.
