The World Boxing Organization says that they have not heard from Floyd Mayweather concerning the WBO title. Mayweather missed Friday's deadline to make a decision regarding the WBO Welterweight Championship. He won that championship from Manny Pacquiao on May 2.
In order to keep the WBO championship, Mayweather would have to fork over 200k in sanctioning fees for the Pacquiao fight and forfeit the WBA/WBC titles at 154. The WBO rules are that you cannot have titles in multiple divisions.
If nothing has been done by Monday, Mayweather will be stripped of the WBO title and Tim Bradley will become the full WBO champion.
