According to an ESPN reporter Ramona Shelburnethis decision may be made for security reasons after Greiner returned from Russia, where she spent 10 months in prison.
Currently, WNBA teams are prohibited from flying charter, even if the owner of the club pays for it. There are significant penalties for violating this rule. The league is ready to allow charters only when all 12 participating teams can pay for such flights.
On December 8, Greiner, who was sentenced in Russia to 9 years on charges of drug smuggling, was released from custody and sent home in exchange for a Russian convicted in the United States, Viktor Bout.
