Chauncey Billups (groin) is without a timetable for his return. Billups returned to practice on Tuesday and Vinny Del Negro said the veteran could play as early as Wednesday, but Billups wound up sitting out and there is now no timetable for his return. "I really don't know. It's a day to day thing," Del Negro said. Billups isn't a lock to return before the postseason, meaning Willie Green will keep his starting spot until Mr. Big Shot is back.
