5 former UFC heavyweight champions Francis Ngannou has defeated

#4. Andrei Arlovski

Arlovski suffered a first round TKO loss at UFC on Fox 23

It is incredible to think that while Francis Ngannou and Andrei Arlovski held the UFC title 15 years apart, the latter is still picking up wins to this day. The two met in 2017 in the midst of a career-worst run for Arlovski, who had lost three straight heading into the bout.

The fight didn't last all that long in truth and was one of the more typical showcases of the freakish power posed by 'The Predator'. He got the win via TKO inside two minutes and earned a performance of the night bonus in the process.

While Arlovski is currently on a two-fight win streak, it is highly unlikely he will get back into title contention at this stage. Instead, the former champion should be appreciated for the entertainment he has provided to his fans with over the years.

#3. Junior dos Santos

Dos Santos suffered a first round round TKO loss at UFC on ESPN 3

Junior dos Santos won the heavyweight championship back in 2011 and continued competing in the UFC until 2020. He faced 'The Predator' in 2019 and in the first of four losing efforts that concluded his decorated run with promotion.

The fight took place in Minneapolis, Minnesota and was another display of the Cameroonian's knockout power. 'The Predator' secured the TKO victory in just over a minute and, once again, earned himself a performance of the night bonus.

Dos Santos has not fought in the octagon since losing to Ciryl Gane in late 2020. More recently, he could be seen as a part of AEW wrestling as part of a group of fighters from the American Top Team led by the gym's head coach, Dan Lambert.
