The NBA has fined Paul George $35,000 after the Los Angeles Clippers star hit out at referees.

George was frustrated with the officiating crew as the Clippers lost to the Denver Nuggets on Tuesday.

George went to the line five times, which he felt was nowhere near enough, and was whistled for a technical foul for arguing with the referees shortly before halftime.

"We played great," George said, per ESPN. "It's tough, the adversity of playing against the extra three [officials]. 

"I thought they were awful... It was bad. Five free throws is very disrespectful on this night. So many times I got hit on layups, 3-pointers, it was constant.

In response, the NBA slapped the forward with a $35,000 fine.

The league's statement added that the fine amount "is based in part on George's history of public criticism of the officiating."
