Measures will be taken to protect players in case of intense heat during 2014 World Cup matches in Brazil, FIFA secretary general Jerome Valcke said here Wednesday.
Heat could become an issue, mainly in the major northern and northeastern cities where matches are scheduled, notably Manaus, Fortaleza, Natal and Recife.
In southern Brazil, this will be less problematic as the months of June and July are the coolest in the year.
Valcke however did not give a precise list of the anti-heat measures being contemplated, saying only they would be left at the discretion of referees depending on weather conditions on the day of the match.
The 2014 World Cup will be played from June 12 to July 13 in 12 host Brazilian cities: Belo Horizonte, Brasilia, Cuiaba, Curitiba, Fortaleza, Manaus, Natal, Porto Alegre, Recife, Rio De Janeiro, Salvador and Sao Paulo.
