Brittney Griner's wife fears that she won't 'know who I'm getting back' once the WNBA star returns from Russia

• Brittney Griner's wife, Cherelle, spoke with Good Morning America's Robin Roberts on Wednesday.
• The WNBA superstar has been wrongfully detained in Russia on drug charges since February 17.

Brittney Griner's wife, Cherelle Griner, has broken her silence on the WNBA superstar's detainment and the fight to bring her home from Russia.

The 6-foot-9 Phoenix Mercury center has been in Russian custody since February 17 after customs agents at a Moscow airport claimed she traveled into the country with hashish oil in her luggage. Now, nearly 100 days later, Cherelle has spoken out about her deep concerns for her wife.

"At this point, I don't even know who I'm getting back when she comes back," Cherelle told Good Morning America's Robin Roberts on Wednesday.

She doesn't know when she'll return, either. Though Griner has made a handful of court appearances in the more than three months since her arrest, a trial date has not yet been set.

Experts previously told Insider they are skeptical that Griner will receive a trial at all, nevermind one in which she's "afforded a fair and equitable legal process."

"Brittney Griner is simply a pawn in a political game — a political prisoner waiting for diplomats from both sides of the former Cold War to find a fair exchange," Esquire Digital Chief Legal Analyst Aron Solomon told Insider.

This uncertainty has taken a toll on Cherelle and almost certainly on Griner. And even though a person close to the situation told Insider back in March that the two-time Olympic gold medalist is doing "OK" considering the circumstances, her wife has indicated that there's no way to be sure.

"I don't truly know [how she's doing]," Cherelle told ESPN's Angela Rye. "I'm in a position of complete vulnerability right now. I have to trust people that I didn't even know until February the 17th, so I'm trusting her lawyers to tell me when they go see her how is her spirit, how is her energy."

"But the truth of the matter is, because I haven't heard her voice myself, I don't 100% know," she added. "But I am being told that she's doing okay."
