Amanda Nunes vs.
Julianna Pena

[{ "selector": ".ziwxe-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".znxaj-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".dkmxx-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }]

Pena undoubtedly claimed the 'Upset of the Year' worthy second-round submission (rear-naked choke) victory over Nunes to become the UFC women's bantamweight champion at UFC 269. [{ "selector": ".mksvo-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(100%)", "opacity": 1}, {"offset": 1, "transform": "translateY(509)", "opacity": 1} ] }]

Conor McGregor vs.
Dustin Poirier 2

[{ "selector": ".ixlmr-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".xvvaj-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".vjopy-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }]

Poirier claimed a spectacular second-round TKO victory over 'The Notorious' one and became the first fighter ever to knock McGregor out in his professional career at UFC 257. [{ "selector": ".fjwon-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(100%)", "opacity": 1}, {"offset": 1, "transform": "translateY(506)", "opacity": 1} ] }]

Jan Blachowicz vs.
Israel Adesanya

[{ "selector": ".veqjp-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".xgqbu-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".ssgvc-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }]

Blachowicz handed Adesanya his first ever professional loss via unanimous decision in their light heavyweight title clash at UFC 259. [{ "selector": ".jlcht-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(100%)", "opacity": 1}, {"offset": 1, "transform": "translateY(529)", "opacity": 1} ] }]

Beneil Dariush vs.
Tony Ferguson

[{ "selector": ".fevuf-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".myojt-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".blxfk-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }]

It wasn't about Dariush defeating Ferguson, but it was about how he won. 'El Cucuy' was utterly dominated and only landed 15 significant strikes in their three rounds of battle at UFC 262. [{ "selector": ".okiwp-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(100%)", "opacity": 1}, {"offset": 1, "transform": "translateY(502)", "opacity": 1} ] }]

Dustin Poirier

[{ "selector": ".sssth-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".yjiun-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }, { "selector": ".voyxi-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "opacity": 0}, {"offset": 1, "opacity": 1} ] }]

Despite being the reigning UFC lightweight champion, Oliveira was favored to lose against Poirier at UFC 269. However, 'Do Bronx' dominated 'The Diamond' and claimed a spectacular third-round submission (rear-naked choke) victory. [{ "selector": ".uvfrq-a", "duration": "500ms", "fill": "forwards", "delay": "0ms", "keyframes": [ {"offset": 0, "transform": "translateY(100%)", "opacity": 1}, {"offset": 1, "transform": "translateY(486)", "opacity": 1} ] }]
