On July 5, the International Football Association Board (IFAB) voted unanimously to allow goal-line technology (GLT) in soccer matches. Rather than selecting one of the two technologies that had undergone rigorous testing, both the Goal-Ref (Germany) and Hawk-Eye (UK) systems will be made available to leagues and associations.
IFAB -- made up of officials from Fédération Internationale de Football Association (FIFA) and the four British football associations -- has stated that the introduction of GLT won't be immediate. Each system will need to be licensed, installed, and tested in each venue that plans to adopt it. IFAB also approved the Additional Assistant Referees system, which allows assistant referees to support referees in a match.
While some leagues may choose to try out GLT within the next six months, FIFA currently plans to introduce GLT in December at the Club World Cup in Tokyo. If all goes well, GLT will move on to the 2013 Confederations Cup and 2014 World Cup matches in Brazil.
