One of the great mysteries in MMA as of late has been the whereabouts of UFC women’s featherweight champion Germaine de Randamie.

Since winning the inaugural title against Holly Holm in February, the Dutch fighter has been relatively silent.

The UFC hoped to book de Randamie vs. Cris “Cyborg” Justino for the belt at UFC 214 in July, however, that fight never materialized.

On Friday, de Randamie’s manager Brian Butler explained to MMAFighting.com why de Randamie is not interested in fighting Justino.

“Germaine and her team have talked, and the position is that she will not fight Cyborg because Cyborg is a known and proven cheater. Even after so much scrutiny has been put on Cyborg, she still managed to pop for something and will always be a person of suspicion who is trying to beat the system rather than just conforming to the rules.

“For that reason, Germaine and her team don't believe that Cyborg should be allowed to compete in the UFC at all. If that is the only fight the UFC wants, then Germaine is willing to wait and see if the UFC will strip her belt before making her next move.”

Justino, considered the best featherweight of all-time, was provisionally suspended by the United States Anti-Doping Agency in December, though after a two-month investigation, she was granted a retroactive therapeutic use exemption (TUE) for Spironolactone, a physician-prescribed diuretic. She did not receive any sanctions from USADA or the UFC.

She tested positive for the anabolic steroid stanozolol in 2011, following her win over Hiroko Yamanka in Strikeforce, and was subsequently suspended for one year by the California State Athletic Commission. To date, that’s the only time Justino has failed a drug test.

The UFC’s next plan for Justino was to book her against Cat Zingano on July 29, however, that fight isn’t finalized just yet. It’s been an eventful week for Justino, the former Invicta champion. She was cited for misdemeanor battery by the Las Vegas Metropolitan Police Department after punching fellow fighter Angela Magaña at the UFC Athlete Retreat on Sunday. Justino was reacting to several unflattering tweets Magaña posted about her. It’s unclear at this time if that incident will affect her next fight.

As for de Randamie, it’s still unclear at this time when she will fight again and whether she’ll still be a champion when she returns to action.

The UFC, aware of de Randamie’s stance, has refused to publicly comment on the situation.
