The event unfortunately took a major hit with the news that Fiziev has withdrawn from the night\u2019s headlining fight <\/a>due to injury, but now both Mateusz Gamrot and Oliveira\u2019s countryman Renato Moicano have raised their hands as candidates for what would be a massive short-notice opportunity. <\/p>\n A former KSW lightweight champion, Gamrot joined the UFC in 2020 and dropped his debut against Guram Kutateladze before going on a four-fight win streak that included three wins via finish. <\/p>\n Rafael Dos Anjos (blue gloves) fights Mateusz Gamrot (red gloves) during UFC 299 at Kayesa Center. \/ Sam Navarro-Imagn Images<\/p>\n An upset-loss to Beneil Dariush at UFC 280 halted Gamrot\u2019s momentum before the 34-year-old won his next three fights, one of which was a UFC Fight Night main event where the aforementioned Fiziev suffered a leg injury just over two minutes into the second round. Following a unanimous decision over former UFC titleholder Rafael dos Anjos, Gamrot lost a split decision to Dan Hooker<\/a> in a matchup that earned \u201cFight of the Night\u201d honors at UFC 305. <\/p>\n READ MORE: Top contender Arman Tsarukyan sleeps ex-UFC champion during wait for UFC title fight<\/a><\/p>\n \u201cGamer\u201d rebounded from the Hooker fight earlier this year when he ended Ludovit Klein\u2019s winning run in a UFC Fight Night co-main event, and the #8-ranked UFC lightweight was quick to express his interest<\/a> in facing Oliveira at UFC Rio following news of Fiziev\u2019s withdrawal.<\/p>\n I’m ready and hungry to jump in!!

A four-fight win streak from 2022 to 2024 set \u201cMoney\u201d up for matchup with Beneil Dariush at UFC 311, and when Arman Tsarukyan pulled out of the card\u2019s main event it set the stage for Moicano to challenge Islam Makhachev<\/a> for the UFC lightweight title. <\/p>\n READ MORE: UFC reportedly books unexpected headliner for one of ESPN’s last UFC Fight Night cards<\/a><\/p>\n Beneil Dariush (red gloves) fights Renato Moicano (blue gloves) during UFC 317 at T-Mobile Arena. \/ Stephen R.
