Ultimate Fighting Championship (UFC) featherweight champion Conor McGregor -- still toiling away at 170 pounds -- was unable to be a guest on the Conan O'Brien late night talk show. But according to "Notorious," he sent "skinny' Nate Diaz in his place.
He's good like that.
Diaz and his "stupid black tee shirt" were making the talk show rounds to promote their upcoming UFC 202 pay-per-view (PPV) event, which takes place Aug. 20, 2016 inside T-Mobile arena in Las Vegas, Nevada. Diaz won their first go-round by way of submission, but McGregor vows to get his revenge.
