Texans running back Arian Foster left Sunday's 23-6 loss to the Minnesota Vikings with an irregular heartbeat.
"I'll be OK," Foster said. "It's a very minor situation, so I'll be OK."
Coach Gary Kubiak said Foster had experienced the problem once before in practice.
"He calms down and he's fine," Kubiak said.
The medical staff told Kubiak that Foster was OK late in Sunday's game and could return. But Kubiak thought it would be best to give him the rest of the game off.
