FIFA have given permission for two different systems to be tested so that the International Football Association Board (IFAB), which oversees the rules of football, can make a decision on goal-line technology at a meeting on July 2.

In England an amateur cup final will try out the Hawkeye system on Wednesday, while in the Danish Superliga, the GoalRef system will be tested when Silkeborg host Sonderjyske on Sunday and in the match between Nordsjaelland and Horsens on May 23.

The Hawkeye system, which has gained international recognition through its use in tennis and cricket, uses a series of cameras to determine the path of the ball and whether it crossed the goal-line.

GoalRef, which has been developed in Germany and Denmark, involves a chip being inserted in the ball, which can be picked up by sensors in the goal posts.

If the ball crosses the goal-line, the referee is alerted immediately.

The referees will not actually use the technology in the three matches.

Instead the systems will be observed by officials who will report back to IFAB.
