NBA Addresses Nikola Jokic-Mat Ishbia Scuffle

In an interview with Pool Report, NBA official Tony Brothers discussed the Game 4 altercation between Phoenix Suns owner Mat ...

...Ishbia and Denver Nuggets player Nikola Jokic with Duane Rankin of the Arizona Republic:

Why did Nikola Jokic receive a technical foul for unsportsmanlike conduct for the fan altercation toward the end of the first half?  

BROTHERS: The ball landed over there in the corner, where it was being held by a supporter. Jokic approached the ball, 

took it from the fan, and then purposefully shoved and knocked him to the ground. 

As a result, he received an unsportsmanlike technical penalty. So he pushed the fan down, right? Yes, brothers. 

Is that the same fan that had the ball, then? BROTHERS: Although the fan no longer held the ball, it was the fan who first had it. 

What prevented him from being sent off instead of receiving the unsportsmanlike technical foul?
