been another fighter that was never knocked down? we all know lamotta went down one time and he was way past it when it happened.
Mayweather claims to have never been down but touched down when he broke his hand against Hernandez, other than that he hasn't been officially down although the Judah touch down was technically a KD not called I thought the Sanders KD should have been called but wasn't
Tua was down vd Rahman in their rematch in d last moment of rd 12 but it was not ruled a KD , later KDd by Barrett as u know (?) . It can b argued that Chuvalo was KDd by Bonavena . Actually it can b argued that McCall went down vs Akinwande (or should have been ruled that way) and I thought only d ropes held him up vs Bruno although he might have been regaining his balance after being flown by a Bruno right hand even if d ropes weren't there .
So far as I can determine, Duilio Loi is the only world champion with more than 100 victories who was never knocked down.
