Ruiz picked the toughest opponent between Usik, Fury and Joshua

Former unified heavyweight world champion Andy Ruiz has shared his thoughts on which of the heavyweight leaders would be his biggest challenge - Oleksandr Usyk, Tyson Fury or Anthony Joshua.

"I'd like to fight all of them, but I think the toughest would be ... Probably Tyson Fury. I think so. It's hard to say because everybody has a plan until they get in the ring and do their thing. And if it doesn't work, what do you do? You need to change your plan for the fight. That's why I once said: "The hardest thing you can do in boxing is to go down or get hurt and then get back up and win, find a way to win." I think I've done that before," the Mexican said in an interview with YouTube channel Fight Hub TV.

As a reminder, Ruiz will fight against Jarrell Miller on August 3 in Los Angeles, USA.
