FIFA have given significant backing to goal-line technology by promising to fund further experiments.
The 10 companies who had presented systems to FIFA last month all failed to meet the criteria, raising fears that Saturday's meeting of the International FA Board, the game's law-making body, will not support further experiments.
But now FIFA secretary general Jerome Valcke has said the world governing body will support new tests. Valcke said following a press conference in Zurich: "The decision is: Do we extend the tests which we at FIFA are ready to do and ready to pay for? "Maybe we will do the next tests in England and in a stadium."
He added: "If something is working then why not? [FIFA president] Sepp Blatter was clear to the executive committee by saying if there is a system that's working we have to accept it."
The meeting of the IFAB in Newport, Wales, will be presented with the results of the tests which took place at FIFA's headquarters in Switzerland.
The goal-line system developed by British company Hawkeye was not one of those tested - theirs needed a stadium environment for their cameras, and FIFA have given them assurances that they are still under consideration.
The IFAB is made up of the four British associations, who each have one vote, and FIFA who have four. Any law change needs at least six votes in favour.
Blatter's decision to re-open experiments into goal-line technology following Frank Lampard's disallowed goal in the World Cup looks to have marked a major shift in attitudes.
The Welsh and Northern Irish FAs, which until now had backed FIFA in opposing any technology at all, are now also leaning towards supporting more tests on goal-line systems.
The 10 systems all had to demonstrate 100% accuracy and that they could transmit the result to the referee within a second of a goal being scored.
