Goal-line technology in football was approved on Thursday by the rule-making International Football Association Board (IFAB) with immediate effect and is to be used for the first time at the Club World Cup in December, dpa reported. Jerome Valcke, general secretary of the governing body FIFA, made the announcement after a special meeting of IFAB which made the historic decision unanimously. In what is the biggest milestone in football since the introduction of yellow and red cards in 1970, two systems - GoalRef and Hawk-Eye - can be used to determine whether a ball has crossed the line or not. The systems require final licensing in stadiums, and if successful at the Club World Cup, are also to be used at the 2013 Confederations cup and 2014 World Cup. -- SPA
