 Bumphus lost the belt to Gene Hatcher in June 1984 in Buffalo, New York.Hatcher scored an 11th-round technical knockout that had Hatcher knocking Bumphus down, then slipping and falling on a follow-up attempt, then throwing Bumphus down to the mat when both fighters clinched.A post-fight melee in the ring then ensued, as Hatcher was celebrating in triumph while the now-deposed champion was slugging away in frustration.
