Shinya Aoki, the reigning lightweight champion for ONE Championship, will return to the cage this May.

Aoki will defend his title against Koji Ando at ONE Championship 28: Warrior’s Quest. The event is set for May 22 from Singapore’s Indoor Stadium.

Aoki (37-6) has picked up seven straight wins since a 2012 loss to Eddie Alvarez while both were competing for Bellator MMA. In December, he submitted Yuki Yamamoto with a twister, pushing his streak of first round submission wins to three.

Ando (11-3-2) is on a five-fight win streak that includes a TKO over Zorobabel Moreira. Four of his last five wins have been finishes.
