As world football moves closer towards embracing the use of more technology in making key decisions that affect the game, assistant referees have been asked to keep their flags down for very tight offside calls.
This according to the FIFA referees committee chairman Pierluigi Collina has been done to enable VAR (Video Assistant Referee) make the correct decision.
"If you see some assistant referee not raising the flag it's not because he's making mistakes. It's because he's respected the instruction to keep the flag down," Collina, the former Italian referee said on Tuesday at the World Cup referees media briefing.
While in Russia, it’s going to be the first World Cup to use the video assistant referee system.
"They were told to keep the flag down when there is a tight offside incident and there could be a very promising attack or a goal-scoring opportunity because if the assistant referee raises the flag then everything is finished," he added.
"If the assistant referee keeps the flag down and the play goes on and maybe a goal comes at the end, there is a chance to review the goal using the technology."
