Can´t believe it either. If this happened it probably was some freak accident or Frazier took it too lightly while Monzon took it very serious. Something like that.
This is one of those persistant boxing myths that refuses to go away, largely due to it's being continually rehashed.
No...Norman MAILER ko'ed Sonny Liston when he drunkenly wandered into Liston's training camp while Liston was training for the first Ali fight. Mailer insisted on putting on the gloves with Sonny, knocked Liston through the ropes seconds later and the "Bear" injured his shoulder in the fall. That's what led to his surrender in Miami...it's true!!!!
one that comes up occasionally is mac foster KOing sonny liston. it didn't happen, they did spar but sonny was getting the better of the exchanges. it happened in 69' when sonny was wayyy past it
