Former World Cup referee Olegario Benquerenca failed the written tests organized by the Referees Committee of the Portuguese Football Federation, according to Lusa and confirmed by a federal source. Benquerenca refereed a quarter-final at the FIFA World Cup 2010 in South Africa and last year ended his international career due to reaching the age limit. He will be replaced from the first division match between Guimaraes and Belenenses scheduled for Sunday, something regretted by the president of the Portuguese Football Referees Association (PAFF). "It's a situation that happens, we all have good days and bad moments. Naturally, in his last year and in his last test, this is not what Olegario would want to have. He must now repeat the test and, within 45 days, will go back to doing what he loves, refereeing", said Jose Gomes Fontelas. International referee between 2001-2014, Olegario Benquerenca, 45, refereed four games in this season's Champions League and two qualifying matches for the 2016 European Championship. At the 2010 FIFA World Cup, he refereed two games in the group stage, Japan-Cameroon and Nigeria-Korea, and the quarter-final Uruguay-Ghana.
