MMA star Cris Cyborg expressed her deep appreciation for what a UFC legend has done for her.

Cyborg had a video conference interview with one of the most popular UFC fighters of all time. Retired MMA fighter Chael Sonnen had the chance to talk to Cyborg a few days ago, and the rare interview was posted by Sonnen on his official Facebook page.

The two MMA stars had a lot of different things to talk about in the interview. And one of the most notable topics of their conversation was the fact that Sonnen did something for Cyborg in the past.

Apparently, Sonnen helped Cyborg’s ex-husband, who was also an MMA fighter, with his recovery due to a severe head injury he sustained in a fight. It was widely known in all MMA that Cyborg’s ex-husband had been in a critical condition after injuring his skull following a loss against Bellator star Michael Page.

Cyborg took the opportunity to thank the UFC legend for providing some financial support during her ex-husband’s recovery.

“I never had the opportunity to tell you thank you sonnen, when my ex had a trauma in his head you gave to him you helped him,” Cyborg said.

In return, Sonnen acknowledged Cyborg with a short but heartfelt message.

“That’s very sweet of, thank you, I hope his doing well,” Sonnen replied.

Looking at the comments section of the post, it appears that Sonnen did not choose to disclose what he had done for Cyborg. Some fans even commented that the 42-year-old MMA legend has been helping other fighters from way back but chooses not to publicize them.

Back in the UFC, Cyborg is officially released by the promotion due to multiple controversies involving UFC President Dana White and UFC star Amanda Nunes.

White has been dealing with Cyborg’s issues in the past few weeks before finally deciding to let go of the Brazilian superstar, MMA Fighting reported.

“All this other bulls—t she’s putting out there, again, to avoid fighting Amanda Nunes . Message received, I get it. I’m going to release her from her contract. I will not match any offers. She is free and clear to go to Bellator or any of these other organizations and fight these easy fights that she wants. Done. Done deal,” White said on Friday.

In his own fashion, White also stated that the release of Cyborg will not only be official, but legal as well.

“I will literally today have my lawyer draft a letter to her team that she is free and clear to go wherever she wants. We’re out of the Cyborg business,” White noted.
