Fan-favourite heavyweight Dave Allen has sparred some of boxing’s best, but ‘The White Rhino’ admits that the man who hit him the hardest came as a ‘surprise’ to him.

This era of the heavyweight division has been governed for the most part by Anthony Joshua, Tyson Fury, Oleksandr Usyk and Deontay Wilder, with Wilder hoping that he can return into heavyweight title contention with a victory over Derek Chisora on Saturday.

Of those names, Allen has sparred all apart from ‘The Bronze Bomber’, as well as a host of other top contenders in the division.

However, on his YouTube channel, when it came to naming the man who hit him the hardest, Allen claimed that Chisora was the biggest puncher that he has faced, much to his surprise.

“I sparred Derek Chisora before the Lucas Browne fight, so probably seven years ago to the week actually. He weren’t in the best shape, I don’t think, and I was fit and I sparred really well.

“But, he hit really hard. I thought he was the powerful puncher that I have ever been in with, just for pure power. Luckily, I could see him coming, because they were wide shots and they were coming from pretty far back and I could brace for them and take a bit off of them.

“In terms of power, he was definitely the biggest puncher that I ever sparred with, really, really heavy-handed. It surprised me because I didn’t think he was a big puncher. I had been watching him and, technically, I thought he didn’t look like he would be a big puncher.”

Chisora will hope to find some of that devastating power when he faces Wilder at the O2 Arena tonight. The Brit says he will retire win, lose or draw, but his 50-fight campaign would be remembered much more favourably if he called time after stopping one of his generation’s biggest names.

Allen returns to action on home soil in Doncaster against Filip Hrgovic on Saturday, May 16.
