Jon Jones (28-1) knocked out Stipe Miocic (20-5) in the third round to retain the heavyweight championship at UFC 309 from Madison Square Garden in New York.

Jones opened with a couple shots up top, a leg kick, and eventually a takedown. On top, Jones worked the ground and pound, refusing to give Miocic any room on the ground in a dominant first round — but while it looked like Jones could have ended it early, Miocic was able to hang on.
