UFC: Junior Dos Santos Says Brock Lesnar Has a "Weak Chin"

The main event of UFC 131 is heating up, as Junior Dos Santos has now taken a verbal swing at former heavyweight champ Brock Lesnar.

Dos Santos' latest comments with The MMA Hour showed how confident he is for the June 11 showdown between the two heavyweight contenders.

“He's a wrestler, so he feels uncomfortable when people throw punches on him.  I think his fight against Cain Velasquez shows good things for me, because I think he's got a weak chin.”

The Brazilian power puncher also had his comments fueled by what Lesnar said in an interview with The Aftermath. 

After acknowledging that his boxing needs improvement, the former “Next Big Thing” went on to say: "As far as learning…I don't know if you ever get used to taking punches, but that's not the problem.”

Lesnar explained his comments by continuing with "The problem is all my other assets have been farther ahead of the game and this is one we're going to have to keep lagging along and not get frustrated and understand I got to get better."

Dos Santos took the former comment to mean that Lesnar cannot take a punch. 

Perhaps even more surprisingly, Dos Santos went on to say that he does not think Brock is capable of overwhelming him with his wrestling in this fight.

"My wrestling is very good and I think it will be hard for him to put me down," he said, also going on to stress that he will be 100 percent prepared and in shape for the fight.

The Brazilian Jiu-Jitsu brown belt continued “If he tries to put me down—for sure he will try—but I will get up and keep the fight [standing]. That's my way to win the fight. I'm looking for the knockout all the time.”

Dos Santos wasn’t done yet though, after emphasizing a speed and experience advantage over the much larger Lesnar, he went on to say, “He's a very good wrestler, a very strong guy, but I think that's not enough to be a complete UFC fighter.”

Bold words from Dos Santos, but his confidence may be justifiable with wins over the likes of Fabricio Werdum, Gabriel Gonzaga and Roy Nelson in the past few years. 

He is also riding a seven-fight win streak and boasts an impressive 12-1 record as a professional fighter. Dos Santos closed the interview by saying that:

“I believe so much in my boxing, and that's going to be the way I will [be] during the fight. I will use my boxing and my footwork to make him feel uncomfortable and then I will throw some punches, and we're going to find out if he is a really tough guy."

Lesnar and Dos Santos are currently coaching opposite each other on Season 13 of The Ultimate Fighter, and their fight on June 11 is one week after TUF finale.
