Which Fighter?

Which fighter was a longtime sparmate for one heavyweight Champ , knocked him down in sparring ,and, had a victory over another, one time heavyweight champ.
????????
nb Both Champs were undisputed titlists.

 

I think I am right in saying the titlists Page was involved with, were not both undisputed,to be honest I suddenly thought of Page when I had put it up ,but no, someone further back in time .

 

Not according to the referee , Harold Valan , this was a bit before that fight.

 

I must be losing it, of course Ellis got the decision against Patterson,along with a broken nose,he never knocked him down though.
Dont think Martin was a spar mate of Ali's though he was of Liston.
BTW Martin was in the US team that the Brits beat 10 -0 NOV 2nd 1961 ,he was stopped in the final rd by Scots John Fisher, with a body shot.Dick McTaggart,and Frankie Taylor were in the UK squad along with Billy Walker,and a young man from Scouseland called Alan Rudkin, who, though down in the 1st went on to stop his man in the final rd, but you knew that ,didn't you.

 

No, Ive seen the last two rounds ,but many years ago.
Harry Carpenter,who did the commenetary, said your Dad was down.
Didnt he look" pro style" there? Those body shots ,you don't see much of that in amateur boxing nowadays.Thanks for posting this :good
