In 2024, the prestige of the Lion Championship was adversely influenced by some unintended incidents. The first is the “West” Rafael Raimond suddenly “disappeared” before the match against Jovidon Khojaev. By the end of the year, in the match deciding on the strategy of the belt, Hoang Thi Nhat Que boxer was over 3.45kg, causing the match between her and Lo Thi Tam to be canceled.
In order to prevent similar cases in the future, Lion Championship has punished individuals, as well as the violating management club in the two incidents mentioned above. In addition, the Lion Championship's competition rules in 2025 also tightened the regulations with these cases.
In case the boxer participating in Lion Championship is a foreigner in Vietnam, they must have time to live continuously for 12 months or more. This is to ensure that all foreign boxers attending Lion Championship have a long -lasting relationship with Vietnam, not “Western backpack” or “mercenaries” short -term, adversely affecting the tournament.
In addition to regulations on foreign boxers, the regulations and sanctions related to weight are particularly strictly applied. Depending on the level of overweight, the boxers to less than 2.5kg may be fined 10% -100% of the bonus. This amount is forced to transfer to the opponent. The game canceled if the boxer was 2.5kg or more, and the boxer and the host club opposite the heavy penalty.
Martial artists to be overweight, even when winning, do not calculate the accumulation points, not rank or receive any title. Their opponent also does not lose ranking if losing. In addition, boxers constantly violating the weight may face a period of time, or lose the ranking position.
