AUSTIN, TEXAS: In a surprising turn of events, a 260-lb bodybuilder Bradley Martyn, who is also a podcast host, found himself pitted against Joe Rogan's 155-lb comedian sidekick Bryan Callen.

However, Bradley Martyn's boastful claims of weighing in at 260 pounds have come under scrutiny after he was found struggling with Callen, who is significantly smaller in weight compared to the former.

For the unversed, in August, Martyn grabbed headlines when he declared he would defeat a professional flyweight boxer in a brawl on the street.

Martyn said he would be able to "lay on top of them" with his power and size. Naturally, his words sparked controversy among professional mixed martial artists and fans.

However, Martyn's comment led to Demetrious Johnson, who is the best flyweight fighter to ever compete in MMA, issuing a challenge to him.

As the Internet buzzes with speculation about a potential showdown between these two athletes, doubts have emerged about Martyn's abilities, especially considering his recent struggles against Rogan's sidekick, Callen.

During an appearance on Henry Cejudo's YouTube channel, former UFC champion Johnson confirmed his intention to take up the challenge.

He mentioned that although he is currently occupied with other commitments, he plans to meet Martyn for the grappling match upon his return.

Johnson got candid about Martyn's claims saying, “It’s funny, you know." He added, “He’s 265 pounds, he’s a bodybuilder, so obviously he has got the weight advantage."

He further added, "But at the end of the day, that’s the beautiful thing about grappling. It’s not about weight, it’s about technique, and we’re going to try to grapple."

“I told Brendan Schaub that I want to make it happen,” he continued, “I’m busy doing other things right now, but when I get back from all my vacation I’m going to fly down to Calabasas and we’re gonna roll, man. I’m gonna roll him up.”

The Martyn-Johnson showdown has generated considerable anticipation among fight fans, as it promises an intriguing clash of skill and strength.

The outcome of this challenge will undoubtedly be closely followed by those interested in the dynamics of combat sports.

Demetrious Johnson claims he's tired of Bradley Martyn's silence

As rumors of a potential confrontation with Demetrious Johnson began to circulate, Bradley Martyn seems to have vanished into thin air.

What began as a podcast conversation about how a bodybuilder would do in a street battle against a fully-fledged martial artist gained traction over the past month when Martyn asserted he would have no trouble taking down the legendary MMA fighter.

On September 5, Johnson provided some insight into what he's done to fulfill his half of the bargain and why he thinks Martyn is just talking during a live stream on 'Mighty Gaming'.

The ONE Championship athlete said, “I’ve already made the case if he wants to do it or not. I have heard nothing from his side. So I’m not going to sit through and follow somebody who doesn’t want to do something. Does that make sense?”

Fans of combat sports and ardent bodybuilders will have to wait to see whether Martyn accepts the call at this time.
