JACKSONVILLE, Fla. -- Khamzat Chimaev stole the show, as expected, at UFC 273 on Saturday night with a unanimous-decision win over Gilbert Burns in what Dana White called one of the greatest fights he's ever seen. Featherweight champ Alexander Volkanovski put on a show of his own with a fourth-round stoppage of Chan Sung Jung. And while Aljamain Sterling may not have silenced all of his critics, his split-decision win over Petr Yan to defend his bantamweight belt likely will shift his focus to a different opponent.
