NOTES: ESPN's Chris Broussard reported that the Cavaliers are shopping G Dion Waiters. A league source refuted the report, saying the Cavs had not made one call about trading him. Waiters said before the game he did not ask to be traded. "I don't know what is going on," he said. He disputed the reported "three-hour meeting" he supposedly had with Cavs general manager Chris Grant. "That's nonsense," he said. ... Former Ohio State C Greg Oden has yet to appear in a game for the Heat. "He's coming along well, very well," Miami coach Erik Spoelstra said. "We're very impressed with the progress he's made." Oden hasn't played since 2009, and there is no timetable for his return. ... Cavs G/F C.J. Miles missed his third consecutive game due to a strained right calf muscle. Undrafted rookie Matthew Dellavedova started the past three games at shooting guard. ... Heat F Shane Battier was held out of the game because of a cold. F Rashard Lewis made his first start of the season.
