Brooklyn Nets guard Kyrie Irving remains unvaccinated, a situation that could prohibit him from playing in home games, Fox Sports reported Thursday.

Local regulations in New York City — and San Francisco — prohibit players from playing and practicing in their home arenas without proof of at least one shot of the COVID-19 vaccine, unless they have an approved exemption, medical or religious.

That's according to a memo the NBA sent to every team earlier this month, which Fox Sports obtained.

Nets general manager Sean Marks said earlier this week that not every Nets player is vaccinated, without addressing Irving or any other player specifically.

"Regarding if they could play today, I can't comment on who could play and so forth," Marks said. "There would obviously be a couple people missing from that picture. I won't get into who it is, but we feel confident in the following several days before camp everybody would be allowed to participate and so forth."

The Nets open camp in San Diego for the first week and play their first preseason game in Los Angeles. There are no such regulations in L.A.

The Golden State Warriors are going through a similar issue with Andrew Wiggins, who has been steadfast against receiving the vaccine.
