The selected FIFA World Cup match officials will attend another dedicated seminar for two weeks at the technical centre of the Italian Football Association in Coverciano. The match officials will be divided into two groups, which will also include video assistant referee (VAR) candidates: CAF and UEFA (16-20 April 2018), AFC, CONCACAF, CONMEBOL and OFC (23-27 April 2018). There has been only one change since the previous seminars: Pawel Gil (POL, photo) replaced Jair Marrufo (USA) on the list of candidates for the VAR designated positions, after Marrufo was included amongst the 36 selected referees.
