The project has already seen some brutal contests.

But it perhaps not yet a moment as alarming as this.

Olson took on Bathory in a women’s lightweight clash.

Bathory aimed a slap on Olson, taking her time to line it up.

She then whacked her opponent with full force, immediately sending her to the floor.

Olson’s eyes momentarily appeared vacant, but she tried to get up nonetheless.

As attendants initially left her to her own devices she inevitably stumbled, falling into a forward roll.

The dazed competitor appeared to lose track of what happened, seemingly laughing at the incident.

As she tried to walk off she was finally seen to by those watching on.

A clip from a rival slap promotion recently caught the attention of Conor McGregor.

Competing in RXF Slap Fighting, competitor Sorin Comsa appeared to have his face disfigured during a hideous contest.
