In March the MMA world was rocked when late replacement Nate Diaz submitted Conor McGregor at the MGM Grand Garden Arena in Las Vegas, Nevada at UFC 196.

The boastful McGregor had moved up 25 pounds for the fight and started out strong, cutting the right eye of Diaz in the first round before gassing out in the second round.  Diaz taunted his rival and landed several big shots before submitting him.

McGregor and Diaz will renew their rivalry on August 20th at the T-Mobile Arena on the Las Vegas strip.  Former boxing welterweight champion Andre Berto said that his friend is taking the rematch much more seriously and that he will be much better prepared for Diaz this time around.

"I talked to him a few days ago. He is doing good. I think that the thing with Conor is that he sensed his mistakes and he texted me after the fight and said that he basically looked past him - that he kind of didn't take the fight too seriously. Now he is really focusing on his boxing and boxing the right kind of guys, tall rangy southpaws. He sounds really confident this time around," Berto told BoxingScene.com.
