An integral part of professional fighting is the ability to take a punch. All fights start standing up, increasing the odds of having you chin tested early in a fight.
The deterioration of fighters' chins come by years of taking punishment. Fighters like Wanderlei Silva, Chuck Liddell and Mirko Cro Cop could not take nearly the amount of damage they could at the end of their career as they did in the beginning.
Fighters presently in the UFC have a wide range of chins, from the weakest, such as Wanderlei Silva, to the strongest, which we will examine by division.
Fighters on this list are only UFC fighters, although guys like Patrick Cote and Fedor Emelianenko definitely contend as top-notch punch takers.
