Fifa president Sepp Blatter and Vice-president Michel Platini have had their appeals against 90-day bans rejected by world football governing body’s appeal committee.
They were suspended in October while Fifa’s ethics committee investigates corruption claims against them.
Blatter is accused of signing a contract “unfavourable” to Fifa and making a “disloyal payment” to Uefa president Platini, but both men deny wrongdoing.
The ethics committee’s investigation focuses on allegations around a 2005 TV rights deal between Fifa and Jack Warner, the former president of CONCACAF, the governing body of football in North and Central America and the Caribbean.
