It was one of the most brutal fights in the sport's history.
Weili Zhang battled it out against Joanna Jedrzejczyk at UFC 248 before coming out on top with a narrow split-decision victory to retain the women's strawweight title.
But when the dust settled, fans were left shocked by the suddenly unrecognisable Jedrzejczyk, who had significant swelling on her forehead from a massive hematoma.
The 32-year-old Polish fighter was rushed to hospital immediately, with ESPN now reporting she has been discharged without any serious injuries.
