Now, after the callouts, BetOnline has released odds for the potential fight: Masvidal is the slight opening favorite at -120, while Diaz is even money.
Masvidal, is coming off of a five-second knockout win over Ben Askren at UFC 239. There, he set the record for the fastest knockout in UFC history when he landed a devastating flying knee. Before that, back in March, he knocked out Darren Till.
