21. Michael Watson (1991)
Watson was an exciting British boxer who saw his life change after one fateful fight. Both Chris Eubank Sr. and Jr. have ended the careers of opponents in a brutal fashion. The elder Eubank fought Watson in 1991 with the WBO middleweight title at stake. It was an opportunity for both men to change their lives. The fight did but not in the way that Watson expected.

One punch changed everything. Watson was ahead on the scorecards and he had Eubank in serious trouble. But then, Eubank connected with a savage uppercut and laid Watson out. He didn’t get up and everybody feared for his health. However, there was incredibly no ambulance or medic at the event. Watson didn’t receive the specialized treatment he needed for almost 30 minutes and the injury unfortunately became life-threatening. After 40 days in a coma, he finally woke up.
