If we would assume McGrain would be the referee, this would be the only example of the referee fighting the two participants!
If I could speak spanish my list would be different but since I dont here it is. Dempsey Fitz Greb Hagler Arguello Rubin Carter or Fritzie Zivic
You will wanna read this @swagdelfadeel, I would wanna invite Klompton, catchwtboxing, inmemoryofjakelamotta, serbianloudmouth, and choklab and we could all sit around and discuss Cleveland Williams, and then my sixth guest would appear...Ha ha.
