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.

World Cup sponsor Visa has made its strongest call yet for FIFA to act against corruption in world soccer, warning it could leave a deal that runs through 2022.

Ahead of Friday's presidential election, Visa said it expected FIFA "to take swift and immediate steps to address these issues within its organization."

"Should FIFA fail to do so, we have informed them that we will reassess our sponsorship," Visa said.

The statement responded to the arrests Wednesday of seven officials in Zurich as part of a U.S. federal investigation of racketeering, money laundering and wire fraud.

Visa re-signed with FIFA last year to cover the 2018 and 2022 World Cups, hosted by Russia and Qatar respectively.

The value of top-tier FIFA sponsor deals is not disclosed. It was valued at around $100 million for the 2014 tournament.

Visa signed in 2007 after FIFA's former financial services partner Mastercard sued for breach of contract.

FIFA paid $90 million to settle that case after a New York judge criticized its business ethics.

The Asian Football Confederation says it still supports Sepp Blatter's bid for another term as FIFA president, and opposes any move to delay Friday's scheduled elections in the wake of a string of corruption arrests of some of the federation's top officials.

In a statement on its website Thursday, the AFC expressed its "disappointment and sadness" at Wednesday's events but also said it "reiterates its decision taken at the AFC Congress in Sao Paulo in 2014 ... to support FIFA President Joseph S. Blatter."

The European federation, UEFA, had called for the elections in Zurich to be postponed due to the arrests and allegations, but the AFC said it was "opposing any delay."

Blatter is seeking a fifth, four-year term in Friday's election. His opponent is Prince Ali of Jordan.
