Former Dallas Cowboys star Michael Irvin is showing a lot of faith in Herschel Walker, the retired football player who is now running for the U.S. Senate seat in Georgia. Speaking with Fox News, Irvin said Walker believes he can do anything, including taking down Mike Tyson in a fight.

“I never doubted Herschel in anything that he has done,” Irvin told Fox News. “One of the first things Herschel said to me was, ‘Mike, you know, I really think I could beat Mike Tyson,’ This was when Mike Tyson was hitting you in the head, and your whole body just exploded. I said, ‘Dude, why you talking like this? What is this? Some death wish? What are you talking about?’ But he was dead serious.”
