Why there is not a third umpire in Hockey or Football sports as it is in Cricket sport?
There is video replay in all common forms of both football and hockey:
- association football has video assistant referees.
- American football has instant replay review; actually performed by the referee rather than a separate official but has the same effect.
- Field hockey has video umpires.
- The NHL has instant replay, either performed by a video goal judge in the arena or by officials at NHL headquarters.
