Dwyane Wade scored 25 for Miami, but with James struggling again, the Heat dropped their third in a row to match their longest losing streak of the season.
James scored 17 points on 8-of-23 shooting and couldn't come through after Miami blew a 12-point lead down the stretch. With a chance to win it at the end of regulation, he got stripped by Butler on a layup attempt.
In overtime, it was all Bulls.
Chicago outscored Miami 9-2, starting with Augustin's three-pointer just under a minute into the extra period. Butler added a jumper from the wing, Noah scored on a putback and Butler added two free throws to make it 95-86 with 1:33 left before James made a layup.
Noah also had seven assists and five blocks with his dad — tennis great Yannick Noah — looking on.
Butler added 16 points and 11 rebounds.
Wade tried to carry the load for Miami, particularly in the early going.
James also played from the start without a mask to protect his broken nose, after ditching it during the previous game. He said it was simply uncomfortable, so he decided to play without it even though he was not cleared to do so.
