So just like Khabib Nurmagomedov's previous 28 opponents, Justin Gaethje knew exactly what was coming tonight - a grappling onslaught.
And just like the other 28, he was powerless to stop it.
In a matter of a few seconds early in the second round of their unification bout, Nurmagomedov dashed Gaethje's hopes of an upset and stretched his unbeaten record to 29-0.
Then during his post-fight interview, the UFC lightweight champion announced he is retiring having promised his mother this would be his last fight after the death of his father and coach in July.
