What Fighters Were Never Beaten...

I think he meant at Junior Lightweight.

 

Roy Jones at HW.

 

You mean LH?

Yes, technically he was never beaten at HW, be that's because he only had one fight...

 

bernard hopkins was defeated as a light heavy

 

.

he beat tarver for the light heavy, and defended his title against winky wright, that's it.

 

He may have alluded to his pro debut, but I think that may have been over the light-heavy limit. But having a record of 2-0 is hardly worth a mention regardless.

 

Foster lost three times at LH, so he doesn't qualify.

JCC was undefeated at 130lbs. So was Arguello, and Mayweather Jr.

 

Mike McCallum at Light Middleweight
Chris Eubank at Middleweight
Steve Collins at Supper Middleweight

 

Now that would have been great to see those guys fight each other, and throw Duran into the mix.

 

I think he meant what he said, man.

Roy lost multiple times at light heavyweight.

Ray Robinson lost as a welterweight, but only when he was fighting a middleweight. Charles dropped a decision in this way as well.

Charles lost over the middleweight limit, effectively losing as a light heavyweight technically speaking.

 

Never saw Ali lose a fight at Flyweight.

Actually there have been plenty of unbeaten alphabet title holders, all starting with the original Queensberry Rules unbeaten World Champion; Jack McAuliffe.

 

Fitzsimmons did lose at Middleweight; and of course lost at Light Heavyweight near the end of his career.

 

He asked what fighters are unbeaten at a certain weight. I answered. The op did not specify how many fights. It it is one, then it is one. If it is 20, then it's 20. Unbeaten is unbeaten.
