It’s no secret that Brock Lesnar’s biggest weakness is his inability to take a punch. Thus, it’s no surprise that heavy-handed Junior dos Santos intends to target Lesnar’s “weak chin” when they meet on June 11 at UFC 131. Dos Santos told MMA Fighting’s Ariel Helwani earlier this week just that and added that he has the ability to shut down Lesnar’s biggest strength – his wrestling.

“He’s a wrestler, so he feels uncomfortable when people throw punches on him,” dos Santos told Helwani. “I think his fight against Cain Velasquez shows good things for me, because I think he’s got a weak chin. I will try to use that, try to throw some punches and…try to use my boxing.”

“My wrestling is very good and I think it will be hard for him to put me down. I will be very prepared. I will be in shape. I have to be one hundred percent in that fight. 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.”

The good news for Lesnar fans is that Brock’s fully aware that getting punched in the face is his kryptonite. The bad news is he doesn’t seem all that confident that he’ll ever get used to it. Instead, he intends to shore up his striking to minimize the opportunities for his opponents to send him flying across the cage. From a recent episode of TUF 13 Aftermath via ProMMANow:

“Obviously as a fighter you want to keep continuing to evolve, and I think as my fights have evolved I have faced guys with better boxing skills and it’s an area I definitely need to work on. As far as learning… I don’t know if you ever get used to taking punches, but that’s not the problem. 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.”

Even if Lesnar’s striking does evolve, the problem is there’s not enough time to get it where it needs to be before he meets the man with arguably the best hands in the heavyweight division. Lesnar is going to have to rely on his takedowns to put JDS on his back and control the fight from there. Otherwise, if JDS is able to stuff Lesnar’s takedowns like he says he can, it’s probably going to be a short and painful night for Brock Lesnar.
