FIFA approved a ban on international matches staged at stadiums over 2,750 metres above sea level without acclimatisation during an executive committee meeting today. “It was decided after talks with FIFA’s medical committee that international games should not be played above 2,750 metres unless there is adequate time to acclimatise,” Blatter told reporters after the meeting in Tokyo, held on the eve of the Club World Cup final between AC Milan and Boca Juniors.“We are not saying it is forbidden to play games above 2,750 metres but that there should be adequate time to acclimatise,” Blatter added, without giving details as to how much acclimatisation would be required.FIFA originally introduced a controversial ruling forbidding games in FIFA competitions being played at more than 2,500 metres in May.
