It will obviously be at 147... But does McGregor fight at 147 in MMA? Is their weight classes the same as baxing? I know nothing about MMA except that the fighters wrestle and rub they groin against each other in their underwear.
Weight classes are different in UFC. McG held belts at fetherweight (145lbs) and lightweight (155lbs) and also fought at welterweight (170lbs) Floyd is in big trouble.
Connor should sign up for boxing and the night of the fight just start sending flying knees etc at Floyd!!!!!! Now I would pay to see that. Plus they would need a huge ref and security guards to make sure none of Floyd's crew could jump in to stop it as well as making sure Floyd doesn't try to escape. Then they should kick the hell out of Connor after the fight to make it fair so nobody can take sides. Seize all the purses and money and give it to charity. Perfect.
