Junto Nakatani has officially vacated his WBC and IBF bantamweight titles as he pursues a megafight with Japanese rival Naoya Inoue.

The two stars will appear in separate bouts on the same card in Riyadh, Saudi Arabia, on December 27 on a stacked bill titled The Ring V: Night of the Samurai.

Further bouts see Kenshiro Teraji up against Willibaldo Garcia, featherweight Reito Tsutsumi, 26-2 (5 KOs), against Leonardo Quintana, 11-1 (5 KOs), Taiga Imanaga, 9-0 (5 KOs), versus Armando Martinez, 16-0 (15 KOs), at lightweight and gifted junior lightweight Hayato Tsutsumi, 8-0 (5 KOs), against Liverpool veteran Jazza Dickens, who is 36-5 (15 KOs).

Inoue is 31-0 (27 KOs) and fresh off a commanding victory over Murodjon Akhmadaliev last weekend in Nagoya. His challenger, Picasso, is 32-0-1 (17 KOs), and he’s been in the frame for Inoue for more than a year.

Teraji, 25-2 (16 KOs), lost his flyweight belt to Ricardo Sandoval in July, while Mexican veteran Garcia is 23-6-2 (13 KOs), and Teraji will fight for the vacant IBF championship at junior bantamweight, after Sandoval defeated rival Rene Calixto Bibiano in May in their rematch.
