Astrid Wett was put through a table by opponent Alexia Grace ahead of their boxing fight on Saturday evening.
The pair's feud began back in May, after an altercation during a press conference for YouTube icon KSI's fight against Joe Fournier.
Security eventually had to break up the altercation between Wett and Grace, with the former boasting a 2-0 record in boxing after wins over Keeley and AJ Bunker.
The OnlyFans model and Chelsea supporter was due to step into the ring for the third time on Saturday evening, in a fight organised by her own boxing promotion.

Grace made her way to the ring well before the 8pm start time, with Wett taking part in a pre-match sparring session.
But then things got ugly after the pair had a row outside the ring at Bronx Gym.

After an initial angry exchange of words between the fighters, Wett then slapped her opponent.
Grace didn't take kindly that, and screamed an expletive in the direction of her opponent before diving on her and pushing her through a nearby table.
She then shouted: "What the f**k is your problem?" before being pulled away from the scene by on-site personnel.
Medical personnel were then quickly called to attend to the 22-year-old, with growing concern for her welfare clearly visible as the clip progresses.

YouTube star Keemstar then posted two photos to his Twitter account which appear to show Wett being placed on a stretcher after the incident.
The live stream of the fight, which was being shown on YouTube, was cut shortly after the incident and has not resumed.
