Ethics investigators for FIFA, the ruling body of world soccer, have recommended sanctions be imposed on Sepp Blatter, the organization’s longtime president, and Michel Platini, the head of soccer’s European confederation, the organization said on Saturday.

Mr. Blatter and Mr. Platini, who have both been provisionally suspended from world soccer since early October as FIFA conducted an internal investigation into a financial transaction between them, will have the opportunity to defend themselves at a hearing, which is expected to take place in December. After that, the judge on FIFA’s ethics committee will decide whether to impose the more permanent sanctions that have been recommended.

In the meantime, Mr. Blatter and Mr. Platini remain forbidden to conduct any business related to the sport. Both men had appealed their provisional bans; earlier last week, FIFA announced that it had denied both appeals.
