The NBA has fined Utah Jazz star Donovan Mitchell $US25,000 after his scathing criticism of officials following his ejection during Wednesday's overtime loss to the Philadelphia 76ers.

Mitchell stormed off the court and kicked a water cooler towards a security guard after he was tossed from the showdown in Philadelphia, where the Eastern Conference-leading 76ers prevailed 131-123 over the Western Conference leaders.

Utah's Mitchell picked up two technical fouls in overtime after 76ers All-Star Joel Embiid had forced OT with a game-tying three-pointer with 5.3 seconds remaining.

Level at 118-118 at the start of overtime, the 76ers went on to outscore NBA leaders the Jazz 13-5 in the additional period before Mitchell unleashed post-game.

"I'm never ever one to blame a ref, blame an official, but this is getting out of hand," Mitchell, who posted 33 points, said after the game.

"There have been games like this we've one. Games we've lost. We're nice, we don't complain, we don't get frustrated, we fight through things.

"But the fact that we continuously get screwed in a way by this . It's getting f****** ridiculous."

Mitchell was fined for public criticism of officiating and his conduct while exiting the playing court, executive vice-president of basketball operations Kiki VanDeWeghe announced.

Jazz team-mate Rudy Gobert was also fined $US20,000 for public criticism of officiating.

Gobert was quoted as saying: "Our guys are not able to get calls everybody else in the f****** league gets. We know we are the Utah Jazz, and maybe some people don't want to see us go as far as we can go, but it's disappointing.

"Three times in a row, Mike Conley is going to the rim, and they're grabbing him right in front of the officials, and there's no calls. And on the other end, there are calls that are invisible that are being made."
