WNBA star Brittney Griner will have a preliminary hearing on Monday morning in Moscow, her lawyer, Alexander Boikov, told ABC News.

Griner has been held in Russia since Feb. 17 on accusations that she was trying to bring vape cartridges with hashish oil into the country. The U.S. Department of State declared in May that officials consider her to be wrongfully detained.

Prosecutors in Russia were granted another extension on June 14 in Griner's case, the Russian state news agency TASS previously reported. Both U.S. officials and sources close to Griner have said they expect Russian courts to keep extending her detention until a deal is reached for her release.

On June 13, officials from the State Department met with Griner's Phoenix Mercury teammates.

"There is a lot involved in getting her back home and safe; they're working relentlessly," Mercury star Diana Taurasi said in a statement released by the team.

Last week, the State Department said a phone call between Griner and her wife was being rescheduled after an earlier attempt to connect on the couple's anniversary failed because of a "logistical error." The State Department and the White House did not offer a date for the rescheduled call.
