William Silva: IBO Continental / Continental North America title
Re: William Silva: IBO Continental / Continental North America title
On a sidenote, which NBA is this whose title was also on the line in that fight? Because Boxrec seems to list it under the same lineage as the NBA from the 30s–40s which became the WBA.
