Amanda Nunes pummeled Raquel Pennington for in excess of 20 grisly minutes on her approach to holding the 135-pound lash.
Nunes returned out of the blue since a split choice win against Valentina Shevchenko in September a year ago and hinted at no losing her status as the best female bantamweight on the planet.
She butchered Pennington with leg kicks before seeming to break her nose with a knee in the secure.
The American, who was battling out of the blue since vanquishing Miesha Tate in late 2016, disclosed to her corner she was done after cycle four yet was sent retreat for greater discipline.
“She was physically in the battle in cycle five however she wasn’t rationally in the battle,” a UFC reporter said.
“We could see, it was directly before us, her nose fundamentally detonated.”
Pennington’s corner confronted quick feedback for advising her to “change her mentality” rather than quit.
