Who are all the fighters Conor McGregor has lost to as of July 2021?

#2 Joe Duffy vs. Conor McGregor at Cage Warriors FC 39

The clash between Duffy and McGregor is reminiscent of a time before Conor McGregor became the face of the UFC and a household name.

In one of McGregor's most devastating losses, Joe Duffy ate Conor McGregor's best shots before forcing the Dubliner into an arm triangle and squeezing out a submission. The fact that all this happened within the span of 38 seconds of the first round is something that still boggles the mind.

#1 Artemji Sitenkov vs. Conor McGregor at Cage of Truth 3

Marking the first loss of his MMA career, a still baby-faced Conor McGregor took on a seemingly harmless opponent in Artemji Sitenkov. Little did he know he would be dealt the first loss of his career.

The fact that this took place in his own hometown of Dublin only makes matters worse. The Lithuanian forced the local hero into a kneebar within a minute of the first round. Conor McGregor was forced to tap out of the fight as soon as Sitenkov got full extension on the submission.
