Jack Dempsey and Banana Sam. Dempsey avoided him like he had the Black Sigatoka after their sparring session.
Tubbs-Ali Green-Holmes Starling and Hearns had a good session which ended up with Marlon's jaw broke.
tyson lewis. i am discounting the 2002 farce. that was a man named tyson. not the tyson that we all fell in love with
Ayala-Cuevas and Czyz. Tony f***** them up royally. Also heard unconfirmed reports of Tony also KO'ing Hearns as well. Whether it actually did happen is anybody's guess, althought it wouldn't surprise me if it did.
theres probably a load that arent known aswell but im not going to give any examples because the only ones i can think of are currently boxing therefor not legends yet and ones already said
McAuliffe owned Dempsey in sparring. Dempsey could only rub McAuliffe's pot belly in admiration afterwards like some kind of Buddha.
Yeah, the Cuevas fight has been shown to be a massive exaggeration multiple times. The Hearn's incident sounds like flat out bull****, considering what an older Hearn's showed in sparring against fighters like Gerald McClellan.
