It's been discussed that JMM would have never lost inside the distance if he were to retire today. Obviously he probably won't retire and he probably will get KO'd or TKO'd at some point in the future but it still struck me as quite an unusual statistic. Are there any notable examples of fighters who have actually retired having never been KO'd or TKO'd? EDIT: I already noted the undefeated ones by the way!
Is hopkins retired? Should he never fight again, hes a modern, non undefeated fighter that fits the bill.
Obviously all the undefeated guys. They never lost. Most of them never took a big enough test to get knocked out anyway.
