Both fighters take risks in catchweight bouts - boxing - ESPN

I guess all these guys too have broken rules in boxing, because they too have fought at catchweights.

Other notable catchweights not mentioned.

Chavez-Whitaker at 145 pounds and the mythical p4p title.

Hopkins-Pavlik and Hopkins-Wright at 170.

Mayweather-Marquez at 144.

Pavlik-Taylor at 166.

I guess all of these guys were breaking the rules of boxing.
