The bout will see Tomoki trying to avenge his very narrow loss to McDonnell from earlier this year and claim the WBA "regular" title. That loss for Tomoki saw him suffering his first defeat as a professional boxer and was a doubly hard hit for him as he was forced to vacate the WBO title prior to that bout due to a ruling from the WBO regarding the WBA's multiple title system.
In the first bout between the two men Tomoki looked the much better fighter in the early part of the bout and even dropped McDonnell early in the contest before being outworked down the stretch and through the middle of the bout. Despite his good start he had, essentially, given the bout away and seemed to not even try to win the final round, a mistake that essentially cost him his unbeaten record.
Even though it seemed that Tomoki threw away the win he did show the typical Kameda arrogance and claimed that he thought he had won every round of the bout. Whilst he clearly hadn't it was the brash attitude that we have come to expect from him and his controversial brothers.
For fans interested in watching this one it will be televised in the US on CBS along with a bout between former world champion Anthony Dirrell and Marco Antonio Rubio.
Having mentioned Tomoki's brothers it is worth noting that we are still awaiting news on Koki Kameda's bout with Kohei Kono, though the speculation is that it could be the final week of September or the first week of October.
