"There was some home-court cooking tonight to say the least," George said after a 110-103 loss to the Sixers. "I mean it was 19 to 11. You all figure out what those numbers are. It was 19 to 11."
The Clippers were whistled for eight more personal fouls than the Sixers.
Kiki VanDeWeghe, the NBA's executive vice president for basketball operations, said the amount of George's fine reflects his prior violations for the same offense.
Overall, George has been fined by the NBA eight times -- for a total of $185,000 -- for criticizing officials. The amount of Thursday's fine matches the $35,000 that he was fined in December 2015.
