Miami Heat coach Stan Van Gundy said it still hasn't been decided when center Shaquille O'Neal will be cleared to return to the lineup.

''We have not decided when he will return,'' Van Gundy said. ``He looked pretty well. He worked on his steps and was moving well. We'll look at him and go over it again [today] and hopefully he'll be OK.''

O'Neal, who has missed the past 18 games with an injured right ankle, practiced Saturday and could play today or no later than Tuesday when the Heat travels to Chicago to face the Bulls.

''I didn't do much running, but it felt good when I was moving straight forward,'' O'Neal said.
