Russian billionaire Mikhail Prokhorov will likely have to wait a little longer to officially become the newest owner of the Nets.

The NBA announced on Thursday that its board of governors probably won't vote next week on whether to approve Prokhorov's deal to buy the franchise as expected.

The league cited the fact that the state of New York has not taken over all the land seized under eminent domain at the site of the team's Barclays Center in Brooklyn.

"The Board will vote on Mr. Prokhorov's purchase of the Nets once a firm date is set for the State of New York to take full possession of the arena site, which the team expects to occur in the near future," said Joel Litvin, the NBA's president of league and basketball operations.

Prokhorov agreed last December to buy 80 percent of the Nets and 45 percent of the new arena from Bruce Ratner's Forest City Ratner Cos.
