Making a 14th UFC appearance – a women’s record – Andrade unloaded a ferocious barrage of punches at the Pole, culminating with a stunning right hand to the jaw to end the contest at 1.58 in the opening round of their lightweight bout at the American Airlines Center in Dallas on Saturday night.
The awesome display of power from the Brazilian, 26, moved her record to 19-6, including 6-1 at strawweight - and had pundits and social media users drooling.
After the impressive display of power, the fighter herself implored UFC chief Dana White to give her a shot at the title against Rose Namajunas as the co-main event to Cris Cyborg versus Amanda Nunes at UFC 232 in December.
“I’m ready, I’m here, I’m ready to take the title,” Andrade said.
Kowalkiewicz later posted a message reassuring fans that she was fine after the brutal KO, expressing disappointment that it “wasn’t her night.”
With the defeat, the Pole, 32, slips to a record of 12-3.
The main event of the night in Dallas saw American Tyron Woodley retain his welterweight belt by beating Britain's Darren Till via second-round submission.
