The welterweight clash between Gilbert Burns and Khamzat Chimaev may not have a title fight attached to it, but the clash between 170-pound contenders is one of the most eagerly anticipated bouts on the card at UFC 273.

Former title challenger Burns faces undefeated Chimaev with both men eyeing a shot at the title. For Chimaev, it’s an opportunity to kick his meteoric rise into light speed by dispensing with one of the most highly respected contenders in the division, while for Burns, it’s a chance to halt the hype train of one of the most talked-about newcomers to the big stage while also moving toward a potential title rematch with reigning champion Kamaru Usman.
