If Kongo gets hit by Mitrione, he won't get up
In his five fights Mitrione’s chin has not really been tested, but that is largely due to the fact that he was too busy pummeling his opponents to get hit.
Kongo won KO of the night honors against Pat Barry but people forget how close he was to losing that fight. Kongo was knocked down and Barry was tenderizing him before Cheick made his big comeback. Kongo was so close to being finished that had the ref stopped the fight I don’t think anyone would have complained. Kongo did however go the distance with champion Cain Velasquez so we know he can take a punch.
Advantage: Mitrione hits harder than Pat Barry, so if Kongo allows himself to be punched as many times as he did in his last fight he may not remember his name afterwards. This will definitely be the biggest test for Mitrione and we will probably find out just how good his chin really is.
Until I see Mitrione hurt in the cage I am going to assume that meaty head of his is pretty solid, but as I said previously, either of these guys can take the other out with one punch, so it will come down to who lands that punch. Slight advantage goes to Mitrione.
