Rockets guard James Harden has been fined $25,000 for publicly criticizing the officiating following Houston's loss to the Los Angeles Lakers on Thursday night, the NBA announced Saturday.

Harden's comments were directed specifically at referee Scott Foster, who he said "for sure" has a "personal" issue with the Rockets and should not be allowed to officiate any more of their games.

Harden was called for four offensive fouls in the loss at Staples Center, including the call that disqualified him from the game with 1:24 left and the Rockets trailing by six points. That call was made by referee Michael Smith, but it was Foster, the crew chief, who was the target of Harden's wrath.

"Scott Foster, man. I never really talk about officiating or anything like that, but just rude and arrogant," said Harden, who finished with 30 points to extend his streak of 30-point performances to 32 games, the second longest in NBA history. "I mean, you aren't able to talk to him throughout the course of the game, and it's like, how do you build that relationship with officials? And it's not even that call [on the sixth foul]. It's just who he is on that floor.

"It's pretty frustrating. And I'm probably going to get hit [with a fine], but honestly, I don't really say anything. I'm a pretty quiet guy, to myself, but it's one of those things where you can't voice your opinion. You can't have a conversation with someone that's officiating the game. You're getting a tech. It's pretty sad."

Harden did not play in the Rockets' 118-112 road win over the Golden State Warriors on Saturday, as he was dealing with flu-like symptoms in addition to a cervical strain in his neck.
