FIFA Refereeing Department headed by Massimo Busacca has invited 52 referees to meet in Rio de Janeiro from 25 to 31 May 2013 at a seminar - among them, there are 50 pre-selected match officials.
"Pre-selected" means that these officials are considered to attend 2014 FIFA World Cup. Two of them, Ali Al Badwawi of UA Emirates will miss the meeting due to injury. At the same time, Argentina's Néstor Pitana and Brazilian official Heber Lopes have been invited, too, despite not being on the prospective list for the World Cup. Khalil Al Ghamdi of Saudi Arabia, who is actually on the pre-list as well, is absent for other reasons.
The seminar comprises basic instructions in terms of the technical application of the laws of the game, briefings and fitness programmes.
