McGregor vows to knockout Mayweather in two

LAS VEGAS— Conor McGregor is convinced he will beat Floyd Mayweather on Aug. 26, inside of four rounds.

And if the Nevada Athletic Commission approves the fighters' request to use eightounce gloves, he said he will beat Mayweather in the first six minutes of the fight.

"He'll be unconscious inside two rounds, really one round, only for the 10-second count I will give him maybe surviving into the second," said McGregor, who enters the boxing world with a 21-3 MMA record. "But if it's 10ounce gloves, maybe four rounds. But under four rounds he'll be unconscious."

But if McGregor plans to fight the same way he worked out for the media on Friday at UFC's exquisite headquarters in southwest Las Vegas, Mayweather shouldn't have any problem improving to 50-0.

The 29-year-old Irishman simulated a 12round boxing match by dancing around punching bags for roughly 47 minutes, at times looking like an out-of-sync boxer with wide swings that left his guard down, awkward combinations and unnecessary shuffling. Other times he looked like an MMA fighter eager to charge his opponent, something he obviously can't do in a boxing match.

But with as much hype and promotion being thrown into the ring with both fighters, McGregor left plenty of intrigue and insists he didn't show half the boxing skills he honed has a youth in Ireland, simply teasing anyone in attendance and everyone else who may have tuned into any livestreaming on social media.
