The blockbuster fight between Terence Crawford and Amir Khan ended in rather controversial fashion. Crawford walked away with possibly the highest profile win of his career but he got that TKO victory via an inadvertent low-blow to Khan. Crawford knocked Khan in the family jewels in the sixth round when Khan's trainer Virgil Hunter threw in the towel. 

Despite the controversial ending, it was simply an anti-climatic finish to an inevitable conclusion. Crawford handled Khan fairly easily during the entire fight up to the low-blow. Considering how easy this fight was for Crawford, he decided to up the ante and call out Errol Spence after the fight, stating: "There's only one fight they are talking about and that's Spence. Whenever they want it, I'm here."
