Philadelphia 76ers hooper Kelly Oubre Jr. and his head coach, Nick Nurse, are gonna have to write out a check to the NBA -- the two were just fined $50,000 each for going ballistic on referees after their 108-107 loss to the Clippers on Wednesday.
The matchup ended in quite the controversy -- the Sixers forward drove to the basket to attempt a game-winning bucket ... and despite making contact with Paul George, a foul wasn't called.
