Las Vegas Aces star A'ja Wilson was brought to tears after seeing Brittney Griner in shackles on Monday -- telling reporters it made her sick to her stomach.
Wilson made the comments just hours after Griner was seen in handcuffs and flanked by guards while at a court in Russia ... getting choked up while talking about it following her game against the L.A. Sparks on Monday night.
"I hated seeing it," Wilson said. "It made my stomach turn."
"That's our sister and I can't imagine what she's going through and I pray every single day that the people that are in high up are doing what they need to do to get her home because it's unacceptable."
The 25-year-old baller prayed the ordeal doesn't put a toll on Griner -- not just physically, but mentally as well.
Griner has been in Russian custody since February -- after she was accused of having hash oil in her luggage at a Moscow airport.
The trial in the 31-year-old Phoenix Mercury star's case is slated to begin Friday. If convicted on the charges, she's facing up to 10 years behind bars.
