UFC superstar Cris Cyborg punches fellow fighter who was constantly at her on Twitter at Athlete Retreat

It all kicked off at the 2017 UFC Athlete Retreat in Las Vegas.

Invicta featherweight champion and former Strikeforce queen Cristiane Justino got into a heated altercation with another fighter on the UFC's roster on Sunday, according to several reports.

Cyborg was supposedly upset over some personal tweets sent by Angela Magana and confronted the strawweight in Sin City. After some words were exchanged, the Brazilian fighter punched Magana in the face. MMA Hour host Ariel Helwani reported that Magana was rocked by the punch, but maintained her footing.

Magana was rocked but didn't fall to the ground. It was broken up after. Cyborg has been very upset about some personal tweets from Magana.

According to UFC strawweight Bec Rawlings, who is a close friend of Magana's, Helwani's claim that she was stunned by the strike was false. The Australia di confirm, however, that the blow left its mark on her lip.  

@arielhelwani Magana was not rocked ?? she took it like a G, but does have a busted lip.

Another detail Helwani didn't mention was the fact that former UFC middleweight champion Chris Weidman tried, and failed, to intervene. His teammate Aljamain Sterling was only delighted to share this news with the world. https://twitter.com/funkmaster_ufc/status/866439369715982336 The All-American later confirmed that he tried to be the hero of the situation, but it just didn't happen for him. https://twitter.com/ChrisWeidmanUFC/status/866439764462911488 https://twitter.com/ChrisWeidmanUFC/status/866440138322198528 Magana, a veteran of The Ultimate Fighter 20, is still on the UFC's roster despite having not competed since 2015. She took to Twitter to refute reports that she called the cops on Cyborg, but revealed that she would be pressing charges against arguably the P4P greatest female fighter in the world. https://twitter.com/AngelaMagana1/status/866490767975501824 https://twitter.com/angelamagana1/status/866487621219893249 Apparently it was one tweet in particular that sparked Cyborg's aggression. Magana sent out a tweet poking fun at Cyborg's appearance using a photo of her visiting cancer patients at a hospital in Brazil. Cyborg’s father is battling cancer and she went dressed as a superhero to visit sick children. https://twitter.com/AngelaMagana1/status/857574824419483649?ref_src=twsrc%5Etfw&ref_url=http%3A%2F%2Fwww.mmafighting.com%2F2017%2F5%2F21%2F15673148%2Fcris-cyborg-angela-magana-involved-in-physical-altercation-at-ufc-athlete-retreat
