Johnny Walker has defended Dominick Reyes against criticism about having a weak chin ahead of their upcoming fight. Walker argues that anyone can be knocked out with the right punch at the right moment, and that the concept of an "iron chin" does not truly exist. He believes knockdowns are not about inherent weakness but about precise timing and placement of strikes. The two light heavyweights are scheduled to face each other this weekend. Walker's comments suggest he respects Reyes' durability despite his recent knockout losses.
