It was a competitive fight with Porter doing better early, but Crawford turning up the heat as the fight wore on. Crawford knocked Porter down twice in round ten. Here is the first knockdown. After the second knockdown, Porter was up, clear eyed and ready to continue, but his father/trainer Kenny Porter stepped up on the ring apron and stopped the fight. Kenny Porter implied afterwards that Shawn Porter's poor training camp was a factor in his decision to cut his son's title opportunity short.
