The hockey World Cup starting at New Delhi later this month will allow players to ask for one referral per match to the video umpire, the games world governing body said today. On the basis of the trial during Champions Trophy in Melbourne last year, each team will be allowed one Team Referral during any match, including extra time periods and penalty stroke competitions, on the award of goals, penalty strokes and penalty corners.Any team player, who is on the pitch at the time of the incident rather than just the captain, can request a Team Referral. The team will retain its right to referral after every successful referral. Besides, the Team Referral, match umpires may also refer decisions to the video umpire when they are not convinced that they have taken, or are able to take, a correct decision relating to the awarding or disallowing of goals.
