[EXCERPT]
Irving earns more than $400,000 per game - and forfeited some $817,000 in salary in January after missing two games to take part in a league-ordered quarantine after attending a birthday party in a club. He earned around $35 million last season, and was slated to earn $36.6 million this year - the last year of his contract.
It’s widely believed that Irving remains the only member of the Nets to not be vaccinated. It was noticed in the media early this week that he didn’t travel with the team for the missed pre-season game. According to ESPN, “The Nets are prevented by law from revealing whether Irving has been vaccinated, but the team’s statement is a strong indication he has not met New York’s vaccination requirement.”
Love to see him win a lawsuit and collect denied backpay.
