"Brittney has always been a good teammate, which is why my role here is to support her and be there for her," said Belyakova, who was also the one-time captain of the Russian national team.
Thursday was Griner's first court appearance after her surprise decision to plead guilty to drug charges last week.
Russian authorities took the Phoenix Mercury star and two-time Olympic gold medalist into custody in February after they said they found vaping cartridges in her luggage containing less than a gram of hashish oil, which is against the law in Russia.
Griner could face as many as 10 years in prison on the charges.

Some U.S. officials have argued that Russia is using the women's basketball star, who played in Russia during the WNBA off-season, as a political pawn.
In May, the U.S. State Department reclassified Griner's case as a "wrongful detention" and the White House has not yet said whether it's considering a possible prisoner exchange to secure her release.
"We urge the U.S. authorities not to exploit this sensitive matter affecting the fates of certain individuals, and we advise them to abandon futile attempts to pressure us," Zakharova said according to The Washington Post.
