UFC fighter Randa Markos has accused her opponent of faking injury and taking a dive to force a DQ win

• Randa Markos has accused Luana Pinheiro of faking an injury to gain a win.
• The two strawweights fought at the UFC's behind-closed-doors event Saturday.
• Markos landed an illegal upkick in the opening round but said Pinheiro oversold the reaction.

UFC fighter Randa Markos has accused her opponent of faking an injury to force a disqualification win.

"I wasn't leaving that cage without a win and she stole that from me," Markos said of Luana Pinheiro two days after their bizarre match at a behind-closed-doors UFC show in Las Vegas.

Markos also seemed to call Pinheiro "little b----."

The two strawweights headlined the preliminary card before the five-bout main card got underway Saturday on ESPN2 and ESPN+.

Their contest was brought to an end after four minutes and 26 seconds, though, when Markos - with her back to the mat - threw an illegal upkick that smacked Pinheiro flush on the jaw.

The impact of the shot sent Luana Pinheiro backward until she collapsed onto the canvas in apparent agony.

"I think we're seeing a little bit of um, what do you call that … acting," the UFC commentator Paul Felder could be heard saying during the broadcast, in a statement he later retracted.

After Markos was thrown out of the match and Pinheiro was awarded the win, the latter was carried out of the arena by one of her coaches. Pinheiro was taken to a local hospital for precautionary measures.

Days later, Markos is seething about the result - particularly as the fight could have been called off earlier after Pinheiro caught Markos with an eye poke.

An Octagonside medical official assessed Markos' eye and as she said she could see well enough to continue, the bout continued.

"I've been in the fight game for a while now. I've never intentionally thrown an illegal blow. It's a fight, s--- is bound to happen," Markos said on Instagram.

"I took three eye pokes (requiring stitches and loss of vision) and never thought for a second that I wasn't going to continue."

On the errant foul, she said: "Yes, my foot grazed her but that my opponent's inability to continue seemed a bit oversold and suspect.

"I let her know after the eye poke that I wasn't leaving that cage without a win and she stole that from me."

Markos, who has now lost four fights in a row, closed by saying she has something in her heart that needs to be let out. And is excited about "whatever is next."

She added: "I'll be back soon."
