The game on the field is regulated by two umpires, one of whom stands behind the wicket at the bowler's end, the other in a position called "square leg". When the bowler delivers the ball, the umpire at the wicket is between the bowler and the non-striker. The umpires confer if there is doubt about playing conditions and can postpone the match by taking the players off the field if necessary, for example rain or deterioration of the light.
Off the field and in televised matches, there is often a third umpire who can make decisions on certain incidents with the aid of video evidence.
Off the field, the match details including runs and dismissals are recorded by two official scorers, one representing each team. The scorers are directed by the hand signals of an umpire.
