<human>:  Why did Conor McGregor lose the UFC fight against Khabib Nurmagomedov?
<bot>: The reason Conor McGregor lost was because he was a bad fighter. He is not very good at fighting, and he didn't do a very good job of defending himself. He was also out-sized and out-muscled by Khabib Nurmagomedov, who is a very good fighter.
