Joakim Noah ditched his crutches Sunday in favor of a large walking boot to protect his severely sprained left ankle, which also will force him out of Tuesday's Game 5 at least.
Noah suffered the ankle sprain in Game 3 and may not be able to return at any point during the current series. Omer Asik started in Noah's place for Game 4.
Game 5 is set to start at 8:30 p.m. CT in Chicago on Tuesday night.
