Khamzat Chimaev is set to face his greatest UFC challenge to date, with promotion president Dana White confirming the fast-rising prospect will take on Gilbert Burns at UFC 273 in April. The bout, originally reported last month by Brazilian news outlet Combate, has been slated for the already stacked April 9 card in Jacksonville, Florida. That event is headlined by featherweight champion Alexander Volkanovski’s title defence against “The Korean Zombie” Jung Chan-sung, with the undisputed bantamweight title clash between Aljamain Sterling and Petr Yan also scheduled. On Tuesday, when previewing this weekend’s UFC 272 in Las Vegas, White told Canadian outlet TSN that Chimaev-Burns was in the pipeline, before confirming to YouTube channel The Underground that “it’s happening” at UFC 273. Undeniably, Burns will represent the most difficult test in <a href="https://www.thenationalnews.com/sport/ufc/2021/08/26/khamzat-chimaev-to-make-comeback-at-ufc-267-in-abu-dhabi/" target="_blank">Chimaev’s breakout UFC career thus far</a>.
