Multi-time kickboxing world champion Marat Grigorian's emotional scars from missing weight for his clash with Japan's Kaito Ono earlier this year still run deep.The Armenian striker and former ONE featherweight kickboxing world title challenger reflected on how the cancelled bout represents a devastating setback in his lengthy journey as a martial artist.While speaking at the ONE 173 press conference in Tokyo yesterday, Marat Grigorian said:"I'm happy to be back. You know, after Kaito cancelled the fight, I was really upset. I really had a hard time at the moment. I had some nights I couldn't sleep because [I was] full of anger and disappointment."He continued:"The painful thing was that I also made the weight, but not at the right time, it was over time. But it is what it is."That experience should serve the former three-time Glory world champion well as he looks to resume his campaign on martial arts' grandest stage later this year.
