Bryant Jennings has insisted he will show Wladimir Klitschko is human after all when the pair meet in New York on Saturday.
American Jennings will enjoy home advantage when he faces Klitschko at Madison Square Garden, with the Ukrainian heavyweight champion fighting in the United States for the first time since 2008, when he beat Russia's Sultan Ibragimov at the same venue.
Jennings will be putting his unbeaten record on the line on Saturday night, which stands at 19 wins with 10 knock-outs, and vowed to show long-reigning champion Klitschko is not as indestructible as he looks.
"He's a human being, it's not like he's some sort of supernatural species," Jennings told Buncey's Boxing Podcast. "You should never put a human being on a pedestal. Of course he's a great fighter and a great athlete, but come on. This is not X-Men, this is not a Marvel comic."
Klitschko was briefly rocked by Kubrat Pulev during his last visit to the ring, before knocking out the Bulgarian in the fifth round. Jennings, who stands at 6ft 3in and weighs around 16st, insisted that any such complacency on Saturday will see the 39-year-old with just his fourth career defeat.
"I've had people who trained with him and they say he works hard and whatever," Jennings said. "But I've actually had people who've trained with me and they say I can match or even top his work ethic. Up until they got to me, Klitschko was the hardest person that they'd seen train until they'd seen the way I get down.
"There's an under-estimation of me. People think 'Oh he's smaller, so he's not that strong'. That's until they get in with me and they say 'wow, this kid is strong as a bull, he works out very hard and he's durable'."
Those words were echoed by British heavyweight David Price, who told Buncey's Boxing Podcast that Jennings' relentless energy gave him a chance against Klitschko, who is nine years his senior.
"His best strength is his engine," Price said. "He's not the biggest heavyweight, but he's really fit and apparently he runs 20 miles a day or something crazy.
"He puts a lot of work in on the road and has good movement with his feet, and every question that's been asked of him, he answers it.
"He's in the position and as deserving as anyone. I rate him as the best American heavyweight, higher than Deontay Wilder as an all-round boxer."
