Nothing in person but following female MMA the last few years I've seen some brutal fights resulting in broken facial bones, huge hematomas and huge gashes and cuts.
But the worst was a bare knuckle championship fight between Christine Ferrea and Jessica Borga. Both of these women were dishing it out to each other when Fereea landed a right hand that broke Jessica's cheekbone, orbital bone and shattered her nose. The punch sounded like a bat connecting with a 100 MPH fast ball. Jessica quickly back pedaled with Chritsine on top ready to finish it but there was no need for another punch. Jessica was on her knees holding her face and shaking . The female ref kneeled in front of her to give the eight count but immediately waved that the fight was over. The ref had a hard time looking at the damage.
As they stood for the winner to be announced you could see the left side of Borga's face was caved in and her nose was pushed beneath her right eye. If you ever heard the threat " ... I'll re-arrange your face ..." , well , this is what they mean by it.
Horrible to see and can't imagine the pain Borga was in then and afterward when they had to pull her nose back into place. She had surgery the next day.
These were two brutally tough women with the worst, most filthy trash-talk I ever heard in the pre-fight press conference. I'll say I doubt Borga will ever be the same fighter after this injury , if she returns at all. I Can't see her ever entering a fight with the same confident, fearless attitude she had before this fight / injury.
After seeing this , I'd never watch another BK fight again.
