Awwal 01, 1432, Feb 04, 2011, SPA -- FIFA's rules-making panel will study the results from 10 different goal-line technology systems being tested before its meeting next month, according to AP. FIFA says the 10 systems will be tested privately next week by researchers from a Zurich-based technology institute. IFAB will meet March 5 in Wales to evaluate how accurate and efficient the systems are before taking a «decision of principle and potential next step» to give referees high-tech help. IFAB also will consider letting UEFA use the five-referee match official system at the 2012 European Championship. Other proposed rules changes relate to stray objects on the field, players wearing snoods and tights, plus referees using vanishing spray to mark where defensive walls stand.
