Head coach Andy Reid said that Rice (hamstring) won't practice Wednesday, Nate Taylor of ESPN.com reports.
Rice emerged from the first quarter of the Chiefs' Week 4 win at Las Vegas with a hamstring injury, but even with the benefit of a Week 5 bye, he hasn't been able to practice in the meantime. He likely will need to mix into drills Thursday and/or Friday to have a chance to return to action Sunday in Seattle.
