There has been a rumour he put him down in sparring when he was an amateur, when Price was the next big thing but it doesn't really mean anything, plus I always heard put him down instead of straight out KO.
I've heard this rumour before, not sure if there's any truth in it. I'd imagine most heavyweights hit the canvas a few times during sparring over the course of a year anyway.
Also fury on talksport saying a young lad called Joshua schooled fury in sparring just before the Olympics
That def happened, I remember listening to Tyson in that interview. Fair play to him for being so honest.
