Additional Information
Injury and Medical Assistance
In case of an injury, the match should be paused for up to 3 minutes, the necessary time for the doctor to provide assistance.
During one round, an athlete may receive medical assistance only twice, and the total time of medical intervention may not exceed six minutes.
A third medical break automatically results in disqualification.
After hearing the doctor’s opinion, the Mat Referee decides on penalties and resumption of the match (note: the cause of the situation must be taken into account).
If the doctor does not allow the athlete to continue due to injury, the opponent wins, provided they did not break the rules. If they did, the injured athlete is declared the winner.
Appeals
After the end of the match, an appeal against the result may be submitted to the Head Referee.
The party filing the appeal must provide a clear video recording of the fight, which will serve as the basis for the decision.
If the Head Referee considers the recording insufficiently clear, the appeal will not be considered.
In case of an appeal against the decision of the match referee, the Head Referee may uphold it or change it if:
The change directly and visibly affects the match result (e.g., point deduction). In such cases, the verdict changes automatically.
The change concerns a disqualification or a decision whose impact on the match cannot be determined (e.g., action interruption). In such cases, the match must be repeated.
In case of an appeal against the decision of the mat judges, the Head Referee may uphold it or order a re-evaluation of the fight based on video footage by three referees.
