IBO/WBA/WBO heavyweight champion Tyson Fury has ripped UFC world champion Conor McGregor.

He feels the popular Irishman tapped too easily on Saturday night in the main event at UFC 196 at the MGM Grand in Las Vegas.  In past interviews Fury accused McGregor of copying him.

After dominating the first round, McGregor was rocked and submitted by Nate Diaz in the second round.

A few days ago McGregor was calling for a "boxing match" with retired pound-for-pound king Floyd Mayweather Jr.

McGregor felt the contest was a 'billion dollar' fight and threatened to rip down every poster featuring Mayweather inside and outside the MGM Grand.

Diaz made a spectacular comeback after getting battered by McGregor's best shots for most of the first 1 ½ rounds. Diaz turned the fight around with a series of big strikes that staggered the featherweight champ. Diaz eventually sinked in a choke, and McGregor taped out.

McGregor started round two with some creative kicks and stance switches. Diaz didn't care, laughing at McGregor's spinning high kick. McGregor landed a shot to the stomach. Diaz's cut over his right eye began to bleed profusely, covering his face with the crimson mask. McGregor peppered Diaz's face with shots. McGregor's hands appeared to be too quick for Diaz's impaired vision.

But Diaz replied with a huge right hand that caught McGregor's attention. Diaz began stalking McGregor midway through the round and landed multiple huge punches. McGregor's mojo slowed, and Diaz got a full head of steam with several hard shots that had McGregor in big trouble. Sensing the end was near, McGregor went for a takedown, and Diaz easily maneuvered into position to finish to batter him on the ground and chock him out.

Fury took to the social networks to give his thoughts on the contest - "Both top UFC fighters lost this weekend, Holly Holm showed more than Conor McGregor. The fighting pride of Ireland would not of tapped out so easy Conor McGregor. I would of went sleep first. There can only be one Tyson Fury."

"If a man talks the bizo then go and back it up. If I say a thing I do it. MMA…..gets hard tap out, boxing is the ultimate combat sport. Where two proper fighters stand up and fight."
