Krystian Czekaj is the current referee and commentator for Kombat Pro Wrestling. He took on both roles beginning with Arena 17 and has been consistently refereeing and commenting ever since. Krystian is the only person on the Polish wrestling scene to serve such a dual duty.
He is also the only Polish referee to sell his own merchandise: a T-shirt saying Sędzia chuj ("Referee dick") - a reference to the crude but popular chant, often heard when the audience is dissatisfied with the ref's decisions, or his apparent lack of perception of heels' dirty tactics.
