They rematched in August, when an improved Kohsaka immediately threw Yvel down, hit him with numerous body punches and submitted him with a toehold for a rope escape; however, the bout was interrupted for Kohsaka falling out the ring in another hip throw, getting injured.
As TK had scored a point before the bout went to no contest, the match was counted as a victory for him. Finally, Yvel and Kohsaka had a rubber match during the King of Kings Tournament, but it was short and uneventful, as TK was stopped again by a bleeding cut.

After a failed takedown, the judoka was caught in a guillotine choke by Frank and had to spend a rope escape.
