I don't know how often this comes up but I will start with Roy Jones Jr. and Montell Griffin. They took each other's undefeated status in back-to-back fights in 1997.
Nice one. Their first two fights were really good. Alvarado was having substance issues and the third bout was a bit of a letdown.
The third was definitely one of the most underwhelming endings of a rivalry, considering how great the other 2 fights were. To be honest there really was no point of a third fight, both guys were already going on a downward path after the second fight.
Tough super lightweight Frankie Warren handed Buddy McGirt his first defeat in 1986. 19 months later McGirt stopped the still undefeated Warren in a world title bout.
Napa Kiatwanchai took the 0 and the minimumweight championship belt from Hiroki Ioka. Two fights later Ioka returned the favor.
