Generally, fighters in the UFC aren't supposed to look like Roy Nelson.
Not in modern-day MMA, at least.
Today, if fighters are competing in the UFC's heaviest division, they usually don't have beards resembling a coral reef or a profile that looks like "Santa Claus on a bender." And they're typically not lugging around huge, sagging beer bellies.
But despite it all, "Big Country" has survived in the world's biggest fight promotion—on the strength of an iron chin, one-punch knockout power and an improbable run on The Ultimate Fighter.
And sadly, Nelson's UFC run may come to an end after his next match.
