When he took a defeat against ferocious challenger Jezreel Corrales in April, Takashi Uchiyama lost multiple things at once, not just the WBA super featherweight belt.

It marked the first "L" for Uchiyama in his professional career, and his consecutive world title defenses was snapped (at 11, two shy of Yoko Gushiken's Japanese record).

But now Uchiyama, 36, actually feels relieved, because he doesn't have to think of different burdens he's shouldered any more but focus on just one thing: to avenge the man who humiliated him.
