NEW YORK (AP) -- Oklahoma City forward Serge Ibaka has been fined $25,000 by the NBA for striking Blake Griffin of the Los Angeles Clippers in the groin area during Sunday's NBA game.

NBA executive vice president for basketball operations Stu Jackson announced the fine on Tuesday. The league also upgraded the Flagrant Foul 1 the Spaniard 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.
