ST. JOSEPH, Mo. (AP) - Pro Bowl running back Jamaal Charles sat out Chiefs practice on Tuesday after straining his right foot the previous day's work out.
Charles was working with the No. 1 offense against the Chiefs' first-team defense near the goal line when he walked toward the medical tent. He spent a couple minutes talking to trainers before climbing into a cart and being driven to the locker room.
Chiefs coach Andy Reid said following the workout that Charles would play in Friday night's preseason game against San Francisco only if he's able.
Charles attended Tuesday's practice but joined the rest of the injured Chiefs away from the practice field. He wasn't wearing a boot and didn't appear to be limping.
