Earlier this week, UFC heavyweight slugger Francis Ngannou called out WWE Universal Champion Brock Lesnar for a fight inside the Octagon.

TMZ Sports caught up with Lesnar’s WWE advocate, Paul Heyman, to get his thoughts on Ngannou – and others, like Olympic gold medalist Kyle Snyder – calling out his client.

Heyman says he’s not surprised that so many people are coming out of the woodwork and throwing Brock Lesnar’s name around. It’s WrestleMania season and Brock Lesnar is the biggest box office attraction in all of professional sports. It’s one thing to throw out empty challenges – it’s another thing to actually stand toe-to-toe with The Beast.

Fans saw on RAW what happened to Roman Reigns when he got too close to Lesnar – and Francis Ngannou wouldn’t fare any better than Reigns did.
