FLOYD MAYWEATHER once dropped a heavyweight in sparring after just 30 seconds with a body shot.
The 45-year-old legend was renowned for his intense training sessions that lasted hours and would even take place in the early hours of the morning.
Mayweather was a pioneer for HBO's '24/7' and Showtime's 'All Access' pre-fight shows that would follow fighters with unprecedented access to their preparation.
But the American would have one restriction - there could be no filming of his sparring sessions.
Former Mayweather training partner Dmitriy Salita, now a promoter, lifted the lid on what went on during these secret spars, as he revealed the five-division champion once floored a cocksure heavyweight with ease.
Salita told EsNews in 2020: "We were at the gym just hanging out, it was after one of Floyd’s fights.
"This guy comes into the gym, a heavyweight and said, 'I wanna get some boxing' and he was just talking a lot of smack.
"There was no-one big enough to spar so Floyd was like, 'Leonard [Ellerbe], get my stuff from the car'.
"Floyd got in the ring with him for 30 seconds and does his shoulder roll and block and just hits the guy with a body shot, and drops him, a heavyweight."
Former sparring partner Salita revealed Mayweather would spar four-minute rounds, with just 15 SECONDS breaks in between.
Mayweather retired officially in 2017 after beating UFC star and ring debutant Conor McGregor, but has had four exhibition bouts since.
He most recently knocked out Japanese MMA contender Miruku Asakura, 30, on a RIZIN bill. That came after facing kickboxer Tenshin Nasukawa, 24, YouTuber Logan Paul, 27, and ex-sparring partner Don Moore.
Now, he returns to the ring on Sunday night in Dubai over eight spectacle rounds against YouTuber Deji.
