Video review technology will be introduced at Wimbledon for the first time this year.
Players will be allowed to challenge certain calls made by the chair umpire - as they are already able to do at both the US Open and the Australian Open.
The technology will be available on Centre Court and Court One throughout the Championships and on the other four show courts when they are hosting singles matches.
It was only last year that the All England Club (AELTC) introduced electronic line calling (ELC), which ended the role played by line judges over the previous 147 years.
