Less than two weeks after he was chosen to be Conor McGregor's replacement opponent, Nate Diaz shocked the new face of the UFC with a second round submission.

Although McGregor was moving up considerably in weight to 170, he was still a heavy favorite in Las Vegas - and on the same night Miesha Tate took Holly Holm's belt, Diaz delivered a result no one saw coming.

It took a matter of seconds for the first McGregor-themed Crying Jordan memes to begin popping up. McGregor's loss comes at a pretty bad time for EA Sports, which is releasing UFC 2 later this month featuring McGregor and Ronda Rousey as cover stars.

McGregor was also roasted by many boxing fans over his recent claim that he "holds the key" to a megafight with Floyd Mayweather.
