‘Wicky Akiyo’ Returns, Faces K-1 Max Star Andy Souwer on Oct. 15 Rizin Grand Prix Card

If the bracket action of two tournaments doesn't get you excited, Rizin Fighting Federation is still trying to keep you happy.

The Japanese promotion has announced an additional bout for its Oct. 15 bill at Marine Messe Fukuoka in Fukuoka, Japan: in a 154-pound contest, K-1 Max and Shoot Boxing star Andy Souwer will have his fifth MMA rules bout, taking on returning cult favorite “Wicky” Akiyo Nishiura. The Oct. 15 card is otherwise built around Rizin's continuing bantamweight grand prix, as well as the kickoff of its 108-pound women's atomweight tournament.

Souwer, 34, is not just a four-time Shoot Boxing S-Cup World Champion, but also a two-time K-1 Max World Grand Prix champion, in addition to his two runner-up finishes in the K-1 Max GP. One of the most achieved and celebrated Dutch kickfighters in history, Souwer has began an MMA career while continuing to compete in the standup realm. Last December, he was armbarred by Kazuyuki Miyata in his third MMA bout, but returned this past May -- his first MMA bout not under the Rizin banner -- and tapped out Massaro Glunder in the third round.

The 34-year-old Nishiura hasn't had an MMA bout in over three years, last putting on the four-ounce gloves in May 2014, when he defeated Ryogo Takahashi in his native Shooto ring. The colorful and violent Japanese veteran's last action period, however, came for Rizin in December 2015 when he was knocked out in the third round of a kickboxing bout with Hiroya.

The Nishiura-Souwer bout will be contested under standard Rizin rules, with a 10-minute opening period and a five-minute second round, allowing stomps and soccer kicks.
