Ultimately, Diaz ended up as the choice, and now he'll get the chance to face McGregor at UFC 196 next weekend. The fight will take place at welterweight with Diaz accepting it on short notice and McGregor happily accepting the move to 170 pounds.
Diaz is no joke. He'a a really tough dude, both mentally and physically. There should be plenty of trash talk before, during and after this fight.
I expect this to be a much tougher fight for McGregor than what was scheduled with Rafael Dos Anjos.
