NBA executive vice president for basketball operations Stu Jackson announced the fine Tuesday. The league also upgraded the flagrant foul 1 Ibaka was given for hitting Griffin as the two battled for position in the paint to a flagrant foul 2, meaning Ibaka should have been ejected from the game.
The incident occurred with 1:52 remaining in the fourth quarter of the Thunder's 108-104 win over the Clippers at Staples Center on Sunday.
"I'm excited that he's playing tonight," Thunder coach Scott Brooks said. "He's a big part of what we do. I respect the league's decision and the review process they go through. I respect it and move on. It's nothing that we worry about. We just focus on tonight's game. That's all we worry about."
