ORLANDO, Fla. — LeBron James isn't used to playing in a nearly empty gym, and it showed Wednesday.

James, who made his debut in front of 15,000 fans at the Pepsi Summer League on Tuesday, played in front of an estimated 150 people Wednesday — and nearly all of them were media or coaches.

He wasn't nearly as sharp and neither were the Cleveland Cavaliers, who lost 82-78 to the Miami Heat. Afterward, James said he won't play the final three games of the Orlando summer league. His agent, Aaron Godwin, said earlier that James would play Thursday against Detroit and Friday against Minnesota, but miss Saturday's finale against Milwaukee to attend a wedding back in Ohio.
