Tests for technology that aims to detect whether a football completely crosses the goal line are set to take place for the first time in an international match on Saturday between England and Belgium at Wembley stadium.
The sport's lawmakers want to make sure the technology, which includes high definition cameras to assist referees in calling a goal or not, is accurate before they officially approve of its usage.
Using an international match is a significant step to reaching a decision. The International Football Association Board will take a vote on the matter in Zurich on July 5.
