Utah Jazz star Donovan Mitchell was scathing in his criticism of officials after he was ejected in the thrilling 131-123 overtime defeat against the Philadelphia 76ers.

Mitchell stormed off the court and kicked a water cooler towards a security guard after he was tossed from Wednesday's showdown in Philadelphia, where the Eastern Conference-leading 76ers prevailed.

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.

"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."

Jazz head coach Quin Snyder added: "The challenge is when you don't get the whistles you want — and those things always happen — is to play through it and continue to compete.

"I thought we did that. Obviously, I heard Donovan's comments. Obviously, there's a level of frustration that he has, that we have, and that's something that presumably you can't control.

"But give Philly credit. Embiid hit a big shot. We were on him trying not to give up a three. And then we weren't able to close the other way and overtime got away from us. We just have to take a break, regroup and continue to compete."

The Jazz (27-9) have lost back-to-back games but still own the NBA's best record as they top the Western Conference heading into the All-Star break.

Philadelphia – riding a two-game winning streak – are half a game clear of the Brooklyn Nets in the east ahead of Sunday's All-Star Game in Atlanta.
