Brittney Griner's 9-year prison sentence in Russia has been upheld ... a court just denied the WNBA star's appeal at a lengthy hearing on Tuesday morning.
The 32-year-old did not appear in person for the proceedings -- but was present via a videoconferencing feed from inside of a cell. She looked downtrodden throughout the process as cameras caught her both sitting and standing behind bars.
Griner and her team of attorneys had hoped officials would overturn a previous ruling in the case, or at the very least, reduce the sentence. They argued the punishment did not fit the crime.
