A little late to this, but I’m assuming that you aren’t trolling the Internet for Sixers stories (or watching their descent into mediocrity on a nightly basis).
Doug Collins was fined $15,000 yesterday for this, calling a referee an "asshole" on Saturday night:
He apologized [via Philly.com]
"I don't ever want to get fined. I've been in the NBA for 40 years," Collins said. "It was sort of a buildup over a few things. It wasn't one thing, it was sort of a buildup. It was an emotional game, and we were able to win the game and stuff. I didn't leave the court in a timely fashion, and I should have been fined. The league did what they should have done, and I apologized."
Your day may now continue without incident.
