Do you mean this accident -
Drooping Face After Slap Fighting Victory?
Yeah, that's terrible, it was brutal. I wouldn't damage my face for thousands, doesn't worth for me to turn into ugly man or get my face nerve damaged. By the way, I have to admit that this sport is very entertaining for me, I have a rush of adrenaline when I watch
Vasily Kamotsky.
It's curious but Bare Knuckle fighting is getting popular too. What's next? Fight without mouthguard? Without groin guard? People are getting crazy, dude.

Yup! That one, his face or head was disfigured for sure he got a nerve or even damage internally but I really hope it is not that severe, actually just seeing his disfigured face brings me the chills, and thinking of watching the power slap would bring me the same sensation as having goosebumps,
Bare Knuckle fighting is still interesting because you will need to be very technical in this fight as well, but people think so much crazy stuff is just unimaginable like they are just crazy thinking something like this that they would likely want a riskier fighting sports than a non-risky ones,
I would choose Football, Basketball, Tennis and some other sports games absolutely every day if I had to make a career. Fighting is brutal, it affects your brain, your face and you get paid small, doesn't worth it.
Power Slap is more dangerous than bare knuckle fights. The argument "you arent allowed to defence" in power slap crosses every single brutality that BK has. Open first indeed may cause lots of visual damage, but the opponent always have a chance to dodge or block to minimize damage. With slaps, it is a little concussion and you arent allowed to defend from it. I think I would better watch kittens fight that watch two men slap each other

To be honest, I like it when they slap each other and then there is a slow motion of how dust and particles leave the face surface and how skin then moves on face like waves in the ocean. Bare Knuckle is just brutal because lack of gloves increase cuts on face, I don't really enjoy it. I don't think anyone will ever make a career in it because injuries will be very frequent and very damaging, there is a very high risk of getting your wrist broken, which means, your career is gone.
