Ibaka tangled with Heat forward James Johnson with 7:50 remaining in the third quarter.
All the movement leaves the defense confused on who to switch to, but before they even get set, the quick go-ahead basket is already made.
Both players were assessed a technical foul and ejected.
A pair of incidents Tuesday involving two Toronto starters have resulted in a one-game suspension of Serge Ibaka and a $25,000 fine for DeMar DeRozan handed down by the National Basketball Association on Wednesday.
Ibaka ($138,357) and Johnson ($96,172) will lose close to $250,000 in salary based on the one-game suspensions.
Johnson, in his ninth season, has been ejected twice previously in his career, both coming past year, his first in Miami.
Guard Tyler Johnson missed the Raptors' game because of a left shoulder strain and he is listed as questionable for tonight. Both players were ejected. He followed that up two days later with a game-high 35 points in a victory over Chicago and added 20 points in a win over the Bucks last Friday.
