Decision Review System (DRS)
The Decision Review System (DRS) is a technology-based process for assisting the match officials with their decision-making.
On-field umpires may consult with the third umpire (an Umpire Review) and players may request that the third umpire consider a decision of the on-field umpires (a Player Review).
The full DRS third umpire protocols can be found in the appendices of each competition’s playing conditions.
