3. Ed Sanders
Ed Sanders was a boxer that competed on the minor level, the professional level, and even in the Olympics.
His first Olympic boxing championship was in the 1952 summer games. He easily knocked out his opponent, Hans Jost, and went on to beat Giacomo DiSegni in his second fight.
On December 12, 1954, Sanders was boxing Willie James. This would be his last fight. During the first ten rounds, the two traded heavy blows.
By the 11th round, Sanders appeared to be tired. James hit Sanders with a punch combination and he fell and lost consciousness.
He never regained consciousness and died after doctors tried to relieve bleeding in his brain.
