Football's law-makers, the International FA Board (IFAB), have announced they will go forward with final tests on two goal-line technology systems ahead of a decision in July.
Calls for goal-line technology to be introduced into the game have grown louder in recent season and series of experiments by scientists in Switzerland have whittled eight contenders to provide such innovation down to two.
The IFAB will now put the remaining systems - one by British company Hawk-Eye and the other developed by German firm GoalRef - through a series of tests .
Hawk-Eye, which is already used in tennis and cricket, is a camera-based system while GoalRef uses a magnetic field with a special ball to identify a goal situation.
The second test phase will take place between now and June and make sure each system is robust enough to remain accurate in a match situation.
FA general secretary Alex Horne told a news conference in Bagshot, Surrey: "It's an important step forward for us but it is important that we do test it for failure. It must be accurate otherwise it won't be worth having.''
Horne said it was ''very unlikely'' that any systems could be in place in the Premier League for the start of next season.
