Ex-FIFA executive committee member Blazer agreed to act undercover for US prosecutors

Former FIFA executive committee member Chuck Blazer agreed to act undercover for U.S. prosecutors and has been co-operating since at least 2011 in the government's investigation of soccer corruption.

Blazer's 19-page plea agreement from Nov. 25, 2013, was unsealed Monday after a federal judge agreed to a request by media organizations. As part of the deal, Blazer agreed he would sign over title of his FIFA pension to satisfy payments owed to the U.S. government.

In exchange for Blazer's co-operation and guilty pleas to 10 counts, the government agreed not to recommend a specific sentence for his crimes and also accepted that a reduction of up to three levels be warranted under sentencing guidelines.

After the corruption investigation became public, FIFA President Sepp Blatter said he would resign.
