With less than 10 days left until a fight in which he'll try to avenge the only loss of his professional career, Shinsuke Yamanaka didn't show any signs of despair, only confidence.

Yamanaka, who will face Luis Nery (25-0, 19 knockouts) in a March 1 rematch at Tokyo's Ryogoku Kokugikan, insisted his training has gone extremely well, maybe even better than previously during his career.

"Ever since I've declared I would continue to box, I've only been thinking of getting revenge against Nery," said Yamanaka (27-1-2, 19 KOs), whose unbeaten record came to an end via a fourth-round TKO against the Mexican last August in Kyoto, during Tuesday's practice at the Teiken Gym.
