Howard, who leads the NBA in technicals this season, was whistled for another one with 1:41 left in the first half Friday night against Chicago.
If the call is upheld following a review by the league, Howard would be suspended for Orlando's next game against Portland on Monday night.
"I think we can live by it and live with [the rule]," Los Angeles Lakers coach Phil Jackson told ESPNLosAngeles before the Lakers' game against Charlotte Friday night. "I hate to see a player miss a game because of it. A player of that caliber and a team that's fighting for a spot at this time of the year, it's going to boil down to an important part of the season. That's a problem."
With the Bulls leading 43-29, the Howard was hit on the top of his head by Kyle Korver as Howard came down with an offensive rebound.
Korver was whistled for a foul, but took a swipe at the ball moments after the play. That prompted Howard to swing his elbows. Referee Ed Malloy stepped in to separate them and also called a technical on Howard.
