Johnny Walker has publicly disagreed with critics who say Dominick Reyes has a weak chin. Walker argued that anyone can be knocked out with the right punch at the right moment, and that there is no such thing as an "iron chin." The two fighters are scheduled to meet this weekend at UFC 327. Walker's comments come as both prepare for their light heavyweight bout. The post also included a poll asking fans who is more likely to score a knockout in the upcoming fight.
