The Heat were one of four Southeast division teams to lose on Friday, although Miami's defeat was the only one of the four to come by more than two points.
Bulls forward Carlos Boozer added 12 rebounds to his team-high 27 points while center Joakim Noah also pitched in 12 boards. Chicago dominated Miami on the glass, particularly on the offensive end, where the Bulls pulled down 19 rebounds compared to the Heat's four.
LeBron James finished with 30 points and six rebounds in the losing effort.
Elsewhere in the Southeast division, the second-place Atlanta Hawks were unable to overcome a lackluster first half in an 85-84 loss to the Detroit Pistons. Atlanta found itself down at halftime, 51-36, and couldn't quite dig completely out of the hole despite outscoring Detroit by 11 points in the final quarter.
Other Southeast division scores from Friday:
Kyrie Irving nailed a 15-foot jumper with one second left to lead the woeful Cavs past the lowly Bobcats in Charlotte.
Joe Johnson hit an 18-footer with 0.7 seconds remaining allowing the Nets to escape D.C. with a win, denying Washington its fifth victory of the season.
