FILE - In this Wednesday, Dec. 18, 2013, file photo, referee Carlos Velasco of Spain marks a line with vanishing spray during the semi final soccer match between Raja Casablanca and Atletico Mineiro at the Club World Cup soccer tournament in Marrakech, Morocco. For the first time at a World Cup, technology will be used to determine whether a ball crosses the goal line during matches at the upcoming tournament in Brazil. With vanishing spray also being used to prevent encroachment by defenders making up a wall during free kicks, officials at the highest level of the world’s most popular sport are finally getting some assistance.
