UFC 273 is in the books. A wild night of action from Jacksonville, Florida, wrapped up with Alexander Volkanovski reminding why he is the top featherweight in the world. The champion dismantled Chan Sung Jung in the main event to retain his title after referee Herb Dean stepped in to stop the bout.

The Australian has now won 21 bouts in a row and 11 straight in UFC.

Elsewhere, Aljamain Sterling silenced his critics with a split decision win over Petr Yan to unify the bantamweight title. Sterling relied on his heavy grappling game to earn early rounds before Yan rallied late. 

And Khamzat Chimaev got all he could handle from Gilbert Burns in a welterweight contest. The rising star faced adversity for the first time as Burns returned fire in some heavy exchanges. Chimaev still got the nod on all three scorecards.
