The Court of Arbitration for Sport says former FIFA President Sepp Blatter has filed an appeal to annul his six-year ban from soccer.

Blatter was banned last year after being found guilty of unethical conduct relating to a 2 million Swiss franc ($2 million) payment by FIFA in 2011 to UEFA President Michel Platini.

An eight-year ban was imposed by FIFA's ethics judge in December, but FIFA's appeal committee reduced it to six years last month.

Platini is also serving a six-year ban and lodged his appeal to CAS last month. CAS is hoping to deliver its verdict in May, a month before the European Championship in France, Platini's home country.
