The system was well-received, catching an offside call just three minutes into the opening match between Qatar and Ecuador.
South Korea also enjoyed a 2-1 victory over Portugal at the Qatar World Cup when Hwang Hee-chan’s goal off a pass from Son Heung-min was determined to be offside by the semi-automated system.
At the Asian Cup in Qatar, the system will show animated signs of offside on the scoreboard.
“The semi-automated offside assistant referee system will take Asia’s already world-class match officials to a higher level,” said Sheikh Salman bin Ebrahim Khalifa, President of the Asian Football Confederation.
The 2023 AFC Asian Cup Qatar will be held in Qatar from January 12 to February 10 next year.
