A UFC fan caught everyone by surprise when he stole the glasses straight off the face of lightweight champion fresh after submitting Dustin Poirier in their UFC 269 title fight.
Oliveira, who was in his first title defence after being Michael Chandler in May, dominated Poirier in a stunning performance.

While the American landed some monster blows early, Oliveira bounced back in a dominant second round and forced Poirier to tap out in the third to claim the huge victory.
But minutes after claiming the famous victory and confirming himself as the world’s best lightweight, a brazen fan tried to get himself a huge souvenir — the glasses right off Oliveira’s face.
Oliveira was draped in a Brazilian flag as he celebrated with fans who knocked his glasses askew before a hand reached out and snatched them off his face.
Oliveira turned straight to the fan as the security guards tried to get his glasses back as he looked to the ground in case the fan had dropped them.
However, he did get his glasses back, although he was wearing sunglasses in the press conference.
“He wanted to take them and wear it,” he said. “We got them back. The security guys from the UFC took them back.”
Oliveira’s eye sight is far from perfect and he wears glasses in order to see properly.
Earlier this week, The Athletic spoke to Oliveira about his eyesight, revealing he is near-sighted and wears glasses.
As his opponents fight him at close range, he can still see kicks and punches with ease but things at a distance are blurry.
“If this is me without having 100 per cent vision, imagine if I had that,” he said through an interpreter.
“My vision never really got in my way. Everyone knows I wear glasses. But when I’m in the Octagon I can see my opponent and I can fight completely normally, so I guess my vision hasn’t gotten in the way of anything so far. I wear glasses all the time and it’s funny that in the fight it’s never been a problem for me. It’s kind of crazy.”
