Whiteside was ejected after elbowing Olynyk in the back of the neck during the third quarter of the Heat’s loss to the Celtics. Last week, Whiteside was ejected and fined $20,000 after tackling Phoenix Suns center Alex Len.
On Tuesday, Whiteside apologized to his teammates for his actions.
“I feel terrible about it,” Whiteside said. “I feel like I let my team down, it can’t happen again. I just want to apologize to everybody.
After playing overseas the previous two seasons, Whiteside has emerged as a key player for the Heat this year. In 35 games, he has averaged 10.9 points, 9.8 rebounds and 2.4 blocks.
The Heat are 28-35 and a half-game behind the Charlotte Hornets for the No. 8 seed in the Eastern Conference. Whiteside will miss Wednesday's game against the Brooklyn Nets as a result of the suspension.
