Has any fighter in history jumped up 2 weight classes after being the Undisputed.....

[jas]

.........champ in a division having been involved in a lineal title fight to then immediately become the universally recognised number 1 in another division the very next bout like Hopkins did after beating Tarver???

i know sugar ray robinson tried but heat exhaustion forced him to quit. (of course super middleweight division wasnt around then but it would have been 2 weight classes if todays divisions existed then)

Spinks against Holmes

Duran against Leonard

Duran did it against Leonard. It's pretty rare though.

I feel wrong to do this, particularly mentioning alongside Duran, but Calzaghe also did it.

[NearHypnos]

well.... SORT OF. Shane was the dude at lightweight then moved up and beat the dude at welter

Calzaghe didnt move up 2 weight classes.

Duran's last fight at 135 was in Februrary 1978. The Leonard fight was in June 1980. He had numerous fights in between, including a fight against a top WW in Carlos Palomino.

I edited OP.

[BennyST]

Ahhh right. Of course. I was just thinking anyone moving up and doing it.

So two divisions, lineal champ in back to back fights? Yeah, very rare.

[BennyST]

Even Mosley had a couple of fights in between.

Didn't Henry Armstrong do it? I know he did it the moving down LW but not sure moving up to WW.
