Instances where two boxers fought early on in their careers and then each went on to have great careers?

Something like Bernard Hopkins fighting Roy Jones Jr fighting in 93 and then each furthering their carees more and then fighting again a decade later.

Or even Usyk and Bertebiev fighting against each other in the Olympics.

I know up and coming prospects aren't usually fed other up and coming prospects, usually just fighters with a ton of losses or washed veterans.
