Perhaps the best pound-for-pound UFC fighter in the world, Conor McGregor has decided to move up two weight classes, to welterweight, in order to fight Nate Diaz in UFC 196. This change comes after Rafael Dos Anjos backed out of the fight against McGregor citing a broken foot.

Now, McGregor is jumping to the 170-pound weight class as the 145-pound champion to fight Diaz.

UFC president Dana White explained the process of finding an opponent for McGregor on SportsCenter:

"We called Jose Aldo; Jose Aldo turned the fight down," White said. "We called Frankie Edgar; Frankie Edgar turned the fight down. Those are two guys everybody was talking about. A lot of guys wanted this fight, but we ended up with Nate Diaz. We felt this was the fight to make and the fight the fans wanted to see."

Holly Holm is also on the card and is set to fight Miesha Tate before the McGregor/Diaz bout.
