Deliberately breaching the contract "never crossed my mind. I'm fully committed to the contract. They had my respect because people knew me from K-1."
The Thai boxer hinted at feeling unease with a change of rules prior to Saturday's fight, saying he had no choice but to abide by it.
"I accepted the rules set by the K-1 committee. They spoke in English but I'm not sure whether my translation was correct or not.
"Since I began fighting in K-1 in 2004, they have banned the use of the elbow but allowed the fighters to use the knee. I knocked out a Japanese opponent with my knee before I went on to win the championship in my first year in sport.
