Johnny Walker defends Dominick Reyes against 'weak chin' claims

Johnny Walker has publicly disagreed with the notion that Dominick Reyes has a weak chin. Walker argued that knockouts are not about having a fragile jaw, but rather about getting hit with the right punch at the right moment. He stated that the concept of an "iron chin" does not really exist, as anyone can be knocked down if caught cleanly. The two fighters are scheduled to meet this weekend. Walker's comments appear to be part of the pre-fight buildup.
