In March and April 1911, Coulon fought Phil McGovern and Harry Forbes in ten round no decision title matches in Kenosha, Wisconsin. Forbes had been recognized as the World Bantamweight Boxing Champion from 1901 to 1903 by the World Boxing Association. Though there was no referee decision on points, if Coulon lost the fight by knockout or technical knockout before the ten rounds were completed, he still would have forfeited his title. Both bouts went the full ten rounds, and several newspapers gave Coulon the edge in the bouts.
