Wrestling is an indoor sport. Apart from the area allocated for wrestling match and viewers, the playing environment involves a jury of three officials −
Referee − The referee controls the action in the center, and blows the whistle to start and stop the action.
Judge − He sits beside the mat to keep score and give occasional approval when required by the referee on various decisions.
Mat chairman − The mat chairman sits at the scoring table and keeps time. He is responsible to declare technical superiority, and supervise the work of the referee and the judge. To call a fall, any two of the three officials must agree.
