Photos from Saturday's UFC 264 event at the T-Mobile Arena in Las Vegas show an American fighter called Jessica Eye bled all over herself and her opponent when her head was split open.

An accidental headbutt during a women's flyweight match against Jennifer Maia left Eye with a gruesome open wound.

The cut did not appear to perturb Eye from fighting, as she showed good striking activity throughout the 15-minute fight, landing 104 shots from 281 attempts (37%) compared to Maia's haul of 102 from 269 (38%).

It was Maia who earned the unanimous decision win, though, in what was ultimately a close match in which Eye showed extraordinary toughness and resilience to fight through an injury that looked horrific on camera.

The wound wept as soon as it was open, as the image below shows:

It left Eye looking like she was wearing a mask of blood:

When the fight was over, Eye looked like she was in her element:

Combat sports physician Dr. David Abbasi called it a "nasty laceration" on Twitter.

He said: "White tissue within [the] cut is periosteum (soft tissue covering) of frontal bone of skull, or actual skull frontal bone itself."
