A look at which UFC weight classes have crowned new champions thus far in 2021.
UFC bantamweight champion: Aljamain Sterling
The Uniondale-raised Aljamain Sterling won the belt from Petr Yan after Yan was disqualified for throwing an illegal knee to the head of Sterling, who was a downed opponent, late in the fourth round. It was the first time a UFC title changed hands via disqualification. Yan was up on two of the three scorecards through the first three rounds, 29-28, 29-28, 28-29, and likely would have won the fourth round if not for committing the illegal strike.
UFC heavyweight champion: Francis Ngannou
Potential reaches actual as Francis Ngannou finally became the UFC heavyweight champion when he knocked out Stipe Miocic in the second round at UFC 260 on March 27. Ngannou, who lost decisively to Miocic the first time they fought for the title in 2018, dropped Miocic twice in the second round, the last of which buckled Miocic's knees to stop the bout.
