WNBA star Brittney Griner will testify in her Moscow drug trial tomorrow.  Griner has been detained in Russia for months after she was found at the airport with less then a gram of cannabis she says was medically prescribed in the U.S.  In Russia, it could carry up to 10 years in prison.  Griner and her lawyers appeared in court earlier today to present evidence and she's expected to be cross-examined tomorrow.  Griner has already pleaded guilty to the drug charge in hopes of getting a shorter sentence or possibly released in a prisoner swap with the U.S.
