The point guard is scheduled to undergo a precautionary MRI today on a muscle just above his left knee. Said Wall, who has started in all 36 games this season, on Saturday: "I know you're going to deal with nagging injuries throughout the year. I'm perfectly fine with that. But ... I can't even bend my knee without it being sore."
