The Mexican in question is 24 year old Southpaw Victor Ruiz (19-5, 14), who has mixed with good company, most notably McWilliams Arroyo and Francisco Rodriguez Jr. He does however lack a signature victory and appears to have beaten mainly limited opposition.
Kameda, like brothers Tomoki and Koki, was banned from fighting in Japan following the bout with Solis. The fight was supposed to be a unification bout between Kameda, the then IBF champion, and Solis, the then WBA champion. Solis however failed to make weight and despite the IBF and Kameda's telling the media that Kameda would be stripped if he lost he managed to retain his title, much to the confusion of the fans, the media and the JBC. The confusion lead to the Kameda gym being stripped of it's license and since then all 3 brothers have signed for American "advisor" Al Haymon.
This will be Daiki's first bout under Haymon and his US debut. On the same card we will see Daiki's younger brother Tomoki fight in a rematch with English Jamie McDonnell with Tomoki looking to avenge his sole career defeat.
Although the Solis controversy was the most recent it wasn't the most notable controversy in Daiki's career. Instead that was his 2007 bout with Daisuke Naito. In that bout Daiki had numerous points deducted in round 12 as he appeared to have a melt down in an attempt to get himself disqualified. The tactics were ones that his father, Shiro, and older brother, Koki, encouraged and punishments were handed down to all 3 men, whilst Naito became a icon for being the first to officially beat one of the Kameda's. It's this bout that really helped set the tone for the Kameda's relationship with Japanese fans who viewed them as the bad boys of Japanese fighting, though at the same time lead them to being among the most viewed Japanese fighters in history, and Naito's subsequent fight with Koki Kameda was a huge ratings success story.
