That means Irving would lose around US$380,000 per game (NZ$545,500) and totalling more than US$15 million (NZ$21.5m) if he goes through the entire season with a jab.
Irving did not appear in person at Nets media day in New York last week which suggests he is unvaccinated.
"I know that I'll be there every day no matter what and just be present for my teammates as one of the leaders on the team and be there for my growing tribe off the court," Irving said in a Zoom interview.
"I know the focus has to be at an all-time high, no distractions. This is the last thing I wanted to create, was more distractions and more hoopla and more drama around this. I'm doing my best to maintain this with good intentions and a good heart."
Despite missing the team media day, Irving travelled to San Diego for the start of the pre-season.
Nets general manager Sean Marks said he expects all the team's players to be vaccinated before the start of the season. The Nets' first home game of the NBA season is against the Charlotte Hornets on October 25.
