Current Undefeated Fighters Who Fought Two Titleholders.......

Danny Garcia? (did Morales have the belt when he fought him?)

 

he lost it on the scales

 

joan guzman (sanchez, barrios)

 

Donaire: Darchinyan, Montiel, Mathebula. (at 3 =/= weights)

edit: forgot Donaire had a L.

 

Chris John?

 

Valero

 

Given the fact Alexander had a gift against Kotelnyk and that Bradley has his against Pacquiao, Bradley actually only defeated one in Junior Witter.

 

Kazuto Ioka for sure
Not sure if Gamboa faced a reigning title-holder aside from Salido
Ditto Ramon Gonzalez
Abner Mares (Perez and Agbeko)
