Fifa president Sepp Blatter and Uefa boss Michel Platini have been suspended for eight years from all football-related activities following an ethics investigation.
They were found guilty of breaches surrounding a £1.3m ($2m) “disloyal payment” made to Platini in 2011.
The Fifa ethics committee found Blatter and Platini had demonstrated an “abusive execution” of their positions.
Both men deny wrongdoing. The bans come into force immediately.
Fifa boss since 1998, Blatter, 79, had already announced he was quitting with a presidential election in February.
Platini, 60, was tipped as a future leader of football’s world governing body and had hoped to succeed Blatter.
A three-time European Footballer of the Year and former captain of France, he had been in charge of Uefa – European football’s governing body – since 2007.
