In the moments leading up to the end of the fight, Markos received an accidental eye poke that warranted a checkup from the cageside doctor.

Following a short break, she indicated she was able to fight on and went straight for Pinheiro, who was making her debut in the UFC.

Markos threw punches until judo black belt Pinheiro tossed her to the octagon canvas.

Once on the ground, she tried to kick Pinheiro away and ended up landing her flush with a second blow while Pinheiro was still down.

Markos' opponent stumbled backward and fell onto her back slowly.

Appearing woozy as the officials attended to her, Pinheiro asked if she had lost the bout.

Referee Mark Smith called the disqualification because he believed Markos' kick was intentional.

Had it been unintentional, the bout would have been dubbed a no-contest as it had taken place in the first two rounds of a three-round fight. 

The official time of Pinheiro's victory was recorded as 4:16 in the first round.

Succumbing to her fifth defeat in her last six shows, Markos was upset at the result and may not be long for the UFC. 

And while Pinheiro was victorious in her maiden outing in the championship, extending her winning streak to seven victories across all competitions, she has come under criticism for her reaction to the kick.

"Nip this b*llshit in the bud before it turns into football (soccer)," one fan demanded, adding of Pinheiro writhing on the floor after the kick: "Nobody wants this feigning cr*p."
