Does Khan really have a glass chin?

[PensionKiller]

losing over 14lbs when you are already low on body fat isn't good. his body and legs were tight and thin. he got hurt by a jab against prescott so something was wrong. freddie stopped him being so top heavy which is good and 140 too. koltelnik hit him ok that before khan could have been dropped with. that being said i feel he can't take a beating
