This is 154 lbs fight, I doubt that Canelo can go down that low. His twin brother in campaigning at 160 lbs. So most likely it will be his brother that Canelo is looking for and not Jermell. Unless either GGG or Canelo beat Jermall, then maybe Jermell can move up to 160 lbs and try to have the narrative of avenging his brother's lost to either of the two.
Yeah, looking for a spectacular performance from him on this fight. He has all the tools to beat Castano with one punch ko.
