Sosa (26-2-1, 14 KO), who holds the tenth place in the world rankings, recorded a weight of 50,300 kg (110.90 lb). Meanwhile, Ioka (17-1, 10 KOs) stopped the scales at 50,800 kg (112 lb) – the category limit.
Officials designated by the WBA will be referee Russell Mora (United States); Judges Levi Martinez (USA), Ignacio Robles (Panama) and Chalerm Prayadsab (Thailand).
This will be the second World title chance for the Argentine, who on June 8, 2013 he was defeated by Juan Carlos Sanchez Jr. for the IBF flyweight belt.
“It’s a tough fight, but I’m prepared 100% to face Ioka. The title will not come easy, “said Sosa.
Meanwhile, Ioka will defend for the first time his reign after dethroning Juan Carlos Reveco on 22 April after a controversial majority decision.
“I am aware of the talent of Sosa. He has a very particular style, is crafty and has a lot of experience. It is a challenge of paramount importance, but go looking for the knockout, “said the monarch.
It is worth mentioning that the winner will face Reveco, who was established as mandatory contender after his loss to Ioka. Should the champion leave with his arm raised, the date of the rematch will be December 31 in Japan.
