The NBA fined David Griffin $50,000 for his "public criticism" over how Zion Williamson was officiated.
Williamson is out indefinitely due to a fractured finger.
"I'm really frustrated because this was avoidable. We told the NBA through every means available to us, through sending in film, through speaking to everybody in the officials department and everybody in basketball operations, that the way they were officiating Zion was going to get him injured.
"Quite frankly, he's injured now because of the open season there's been on Zion Williamson in the paint. He's been absolutely mauled in the paint on a regular basis, to the point that other players have said to him, 'I'm going to keep doing this to you because they don't call it.' There's more violence encouraged in the paint against Zion Williamson than any player I've seen since Shaq. It was egregious and horrific then, and the same is true now," said Griffin on Friday.
