As part of the incident, Livingston and Kirkland bumped heads.
The altercation started when Livingston aggressively approached Kirkland as he protested a non-call in the Warriors' 123-95 win over the Heat, NBA officials said. Livingston was ejected from the game.
Though, the more interesting aspect of the NBA's decision is that it has removed Kirkland from officiating Association games for the next week. But this was the odd case where the official assumed partial responsibility, and was therefore also disciplined by the National Basketball Association. After getting tossed from the game, Livingston untucked his white jersey as he walked off the court.
Displeased with the fact that a foul was not called on his shot attempt, Livingston began to argue with the referee on the baseline while the ball was still in play.
The big question was whether Livingston or Kirkland initiated contact.
Warriors forward Kevin Durant suggested as much after the game, per Mark Medina of the Mercury News: "It did look like, watching it, that Courtney stepped into his face". There was 6:24 left in the second quarter at the time. Plenty of other players, including Andre Iguodala, Patrick McCaw and Draymond Green, can also initiate the offense.
