Cris Cyborg and Amanda Nunes are expected to go head to head in a UFC super fight later this year.
But the timing of that bout has upset the women's featherweight champion.
CYBORG WANTS THE FIGHT SOONER
It's proposed to take place on December 30, 12 months after Nunes first challenged Cyborg back in 2017.
Understandably, Cyborg wants it done sooner - she hasn't been in the cage since March this year - and for someone at the peak of their career, that's frustrating.
So frustrating, in fact, that the 33-year-old has taken to Twitter to voice her opinions on the situation.
She quoted a tweet from ESPN giving an update on her proposed fight with Nunes, offering her side of things.
"I am healthy and ready to fight now. 10 months is a long time to be outside of the cage in the prime of your career when you are healthy and ready to fight," Cyborg wrote.
She's clearly upset with the UFC for scheduling this match for the end of the year. So much so in fact, that her MMA future is in doubt.
CYBORG'S LAST UFC FIGHT?
As well as voicing her frustration on Twitter, the featherweight champ recently did an interview with Globo’s Combate website - suggesting that Nunes could be her last fight.
"I think this fight will be my last in the UFC," Cyborg told them, per MMAMania.
"My contract goes until March and I'm doing this fight in December, I think it will be the last one the guys will see me fight."
Judging by that statement, Cyborg seems completely uninterested in signing a new deal with UFC after her current one expires in 2019.
If she does leave after fighting Nunes - and indeed beats the UFC Women's Bantamweight Champion, she'll go down as one of the promotions best female fighters.
Her current record stands at 20-1, with one no contest. If she can take it to 21-1, Cyborg could well be following Ronda Rousey into the Hall of Fame if she does decide to leave UFC next year.
