"FIFA is not considering changing the dates of the 2022 World Cup in Qatar despite fears the intense heat poses a serious health risk if the tournament is played in summer.
FIFA general secretary Jerome Valcke said Monday that he accepts "worries about the heat are legitimate" but adds that the intention remains "to play this World Cup in June."
Before the World Cup vote, FIFA's technical report labeled Qatar's heat a "potential health risk."
