No way the loser of this fight risks another loss to a 40 year old Ortiz coming off a KO.
Especially if it's Joshua.
If Joshua beats Ortiz, people won't give him proper credit. And if he loses to Ortiz coming off two losses in a row to Ruiz, he's done. It's a lose/lose, and it's why not a lot of top fighters want to mess with Ortiz. Not super popular, doesn't speak English, old, chubby, tricky southpaw with KO power.
I would love to see it happen but I just don't think it will. If I were Hearn I definitely wouldn't send Joshua out there against another power puncher coming off two losses in a row to Ruiz.
