In the Lakers' telecast, you can see Blake walking toward the sidelines and talking to a fan while Chris Paul shoots free throws, but the incident in question comes a few seconds later.
After fouling out late in their 105-95 loss to the Clippers, Blake appears to be shouting across the court at someone. Instead of taking his place on the bench, Blake walks to the other side of the court, where he continues talking to a fan in the front row.
Blake finally did take his seat, but from there he continued to shout across the court from the team's bench.
Blake met with Steve Jackson, the fan he yelled at, at the Lakers' practice facility on Tuesday to apologize.
"We got a chance to speak and talk about the situation. I just let him know that I was sorry for the way I acted. I didn't handle myself the way I wanted to. We were able to talk and hopefully build a relationship off of that."
After meeting with the fan, Blake noted that he was caught up in the moment and that, "It was a spur-of-the-moment bad decision."
NBA Executive Vice President of Basketball Operations Stu Jackson described the violation as, "directing inappropriate language toward a fan."
For a few choice words, Blake was fined a hefty $25,000.
According to the Los Angeles Times, the fan shouted at Blake, "You need to knock down those open shots," to which Blake responded with some less-than-savory language.
Blake had missed two jumpers in the final 1:30 of the game—one three-pointer and a long-range shot—and finished the game with eight points on 2-of-6 shooting.
He was starting in place of the injured Steve Nash, who has been out since Los Angeles' second game of the season with a non-displaced fracture in his fibula.
It was a sign of frustration from the Lakers player as his team was on their way to a third-straight loss and a second by double-digits.
