I won my title from a legendary fighter, but I am also known for having an iron set of whiskers...For sure...Who was I ???
Again, this can be several. Sandy Saddler, Lou Ambers and Battling Nelson are a few. If I had to guess, knowing how you think, I will go with Nelson.
HH you figured that out..Yes it is Eugene Criqui, who while a French soldier in Verdun,in WW ONE,had his jaw completely shattered by a snipers bullet..Army surgeons reconsrtucted his jaw with a silver plate,and after the Warvended Criqui resumed his career and won the featherweight crown from the great Johnny Dundee in 1923..Criqui had 130 bouts with this metal plate...Amazing !!!
