Andy Ruiz insists he expects a new style from Anthony Joshua in their world heavyweight title rematch.
The Mexican-American stunned the world of boxing by knocking out AJ in June.
And the champion now expects the Briton to mix it up in pursuit of recapturing his belts.
“We’ve got sparring partners running around and being slick,” Ruiz Jr told Sky Sports.
“A lot of people came to me and said that they wanted to help, like Michael Hunter.
“The only thing I’m doing differently is sparring. I’ve got a lot of different sparring partners in case he tries to switch his style up – in case he tries to box, or keep me away with the jab. We’re practicing.
“I’ve had an almost three-month camp for this fight. We’ve got more things done. We’ve practiced what AJ is going to do.”
Joshua, too, has been prioritising sparring, revealing his partners have been “giving him hell”.
Joshua told Sky Sports: “Up the sparring, that’s the best way to prepare for a fight. Up the sparring partners.
“They’ve been giving me hell. That’s the closest thing to a fight – we’ve been sparring for a long period of time and it gets you battle-hardened. I feel tough.
“Aches and pains, but for the right reasons. The punches get you battle-ready.”
