To what end? In other words, why would he lie about losing a fight as an amateur? There is no reason to. Byrd said he had never met Joe in the ring or otherwise.
I read a letter that Byrd sent to Flatlander in which he claims him and Calzaghe never met in or outside the ring.
Not sure to what you are referring too but Chris is not a liar. I am still waiting for someone to tell me what would be the point of advantage to Byrd to lie about something like this.
