Kyrie Irving Fined $50k, Forfeits More Than $800k For Maskless Partying

Kyrie Irving has been hit with yet another fine this season ... this time, the Brooklyn Nets superstar will have to cough up $50,000 for violating the league's health and safety protocols.

As we previously reported, the NBA was investigating video of a maskless Irving attending a private birthday party for his sister earlier this week, which is against the league's COVID-19 policy.

The rule states players cannot attend indoor events exceeding 15 people.

The Association handed down its punishment Friday ... and while KI was hit with the $50k fine, he will also forfeit game checks for the 2 games he missed following the party, which amounts to $816,898, according to insider Bobby Marks.

It's not the first time Irving has had to pull out his wallet this season ... he was fined $25k for refusing to speak to the media.

The latest development adds to the drama-filled season for Irving -- who went MIA on the Nets last week for "personal reasons."
