FIFA President Sepp Blatter has cancelled another speaking engagement as he avoids appearing in public for a second day.

FIFA says Blatter will not give a scheduled speech to open Thursday's session of a soccer medical conference in a Zurich hotel.

Blatter skipped two meetings of continental soccer organizations on Wednesday. He typically would attend those ahead of Friday's annual congress of FIFA's 209 member federations.

The FIFA president would usually follow protocol and attend the UEFA meeting scheduled 12:30 p.m. (1030 GMT) Thursday.

However, UEFA leaders want to postpone the presidential election amid turmoil in world soccer after federal investigations by the United States and Swiss authorities hit FIFA on Wednesday.

UEFA is supporting Blatter's election opponent, FIFA vice president Prince Ali bin al-Hussein of Jordan.
