Spence was already #1 for WBC because Thurman is injured. Fundora is unified WBO/WBC.
What are you talking about. Tsyzu vs Thurman was not for a belt. Neither Thurman or Spence are ranked at 154.
I think your getting confused that Spence was ordered to fight Thurman by the WBC that was at 147.
Spence does not deserve a fight vs Fundora, at all.
