Paulo Costa was originally scheduled to fight newcomer Ikram Aliskerov at The Delta Center in Salt Lake City, Utah at UFC 291. However, with less a fortnight remaining, the card has now seen a huge change as Costa was replaced by Roman Dolidze.Spinnin Backfist@SpinninBackfistIkram Aliskerov vs Paulo Costa is OFF according to Ikram’s campthe new fight that is in the works is Ikram Aliskerov vs Roman Dolidzeper @judobetter9953036127Ikram Aliskerov vs Paulo Costa is OFF according to Ikram’s campthe new fight that is in the works is Ikram Aliskerov vs Roman Dolidzeper @judobetter995 https://t.co/iMUgCHN1LCWhile Paulo Costa didn't initially provide any reason for the pullout, he now seems to have hinted at a new booking. @MMAPauli on Twitter reported that 'Borrachinha' has been booked for a high-caliber clash against Khamzat Chimaev at UFC 294 in Abu Dhabi in October. Responding to the tweet, Costa wrote:"Pauli is smart enough 🙏🏼🧃👀🧢"Paulo Costa ( Borrachinha )@BorrachinhaMMAPauli is smart enough 🏼🧃🧢 twitter.com/mmapauli/statu…Pauli.♤@MMAPauliPaulo Costa fight is off because he’s fighting Khamzat Chimaev in Abu Dhabi. #UFC294166973Paulo Costa fight is off because he’s fighting Khamzat Chimaev in Abu Dhabi. #UFC294 https://t.co/q5boGC7AZmPauli is smart enough 🙏🏼🧃👀🧢 twitter.com/mmapauli/statu…While Ikram Aliskerov is only one fight old in the UFC, the Russian is currently riding a six-fight winning streak. His lone professional loss dates back to a 2019 decision against Khamzat Chimaev, which 'Borz' acknowledges as the toughest fight of his career.If Paulo Costa has indeed secured a booking against Chimaev, it is certainly a smarter choice for the Brazilian, given Aliskerov appears to be almost as dangerous as 'Borz' minus the clout.Meanwhile, 'Borrachinha' is coming off a bizarre decision win over Luke Rockhold in August 2022 that snapped a two-fight skid.
