Quick read
Johnny Walker rejected the notion that Dominick Reyes has a weak chin, arguing that anyone can be knocked out with the right punch at the right moment. Walker stated that there is no such thing as an "iron chin" and that vulnerability to knockouts is universal in fighting. The two light heavyweights are scheduled to face each other this upcoming weekend. Walker's comments suggest he views Reyes as a credible threat despite past knockout losses.
