On Saturday, the 25-year-old Brooklyn native defeated Taylor to win the WBO belt in the 63.5 kg weight class. Previously, after defeating Vasily Lomachenko, he also became the unified lightweight champion.
Yesterday, Lopez officially informed the World Boxing Organization that he was relinquishing his title. This information was confirmed by Francisco "Paco" Valcarcel, President of the WBO.
In the previous WBO rankings, Arnold Barbosa (28-0, 10 KOs) and Jose Ramirez (28-1, 18 KOs) were in the first two places. However, it is not yet known whether they will be assigned to fight for the now vacant trophy.
