Junior bantamweight titlist Liborio Solis failed to make weight on Monday and was stripped of his world title on the eve of a unification showdown with fellow titleholder Daiki Kameda.
Solis and Kameda are due to meet Tuesday at the Bodymaker Colosseum in Osaka, Japan, Kameda's hometown, but Solis can no longer win either title. If Kameda wins, he will add the now-vacant belt to his collection.
Solis (15-3-1, 7 KOs), 31, of Venezuela, initially weighed in at 118 pounds, three over the division limit. On his second try, Solis weighed 117½ pounds but he did not make a third attempt within the allotted time he was allowed.
Kameda (29-3, 18 KOs), 24, a former flyweight titlist, won a vacant junior bantamweight title by unanimous decision against Rodrigo Guerrero of Mexico on Sept. 3 and was to make his first defense against Solis.
Solis won his version of the 115-pound title via majority decision against Japan's Kohei Kono in Tokyo on May 6 -- a fight in which both men were knocked down -- and was also due to make his first defense in the unification match against Kameda.
Kameda and his brothers, Koki and Tomoki, made boxing history in September when Daiki beat Guerrero, making it the first time in that three brothers simultaneously held world titles. Tomoki Kameda won a bantamweight title in August and Koki Kameda, who has won world titles in three weight classes, also holds a bantamweight world title
