yes he does and beats him with ease but im not sure what weight that fight would take place at because he fought khan at lightweight in 2009. at that time naz had been retired for over 7 years and was probably 13+ stones. so in your imaginary world what catchweight could they fight at? meet at middleweight?
I don't know if Hamed's size and style would of worked up at lightweight. He wasn't really a big fella.
