Chuck Blazer has told The Associated Press he is resigning as the No. 2 official of CONCACAF in December, a half-year after going public with bribery accusations against his then-boss.

The 56-year-old American has been secretary general of the Confederation of North and Central American and Caribbean Football since 1990. He said in May that CONCACAF president Jack Warner and Asian confederation head Mohamed bin Hammam attempted to bribe Caribbean delegates $40,000 each to vote for Bin Hamman in the FIFA presidential election.

After Blazer made the charges, Bin Hamman withdrew, leaving Sepp Blatter to run unopposed for a fourth term. Warner resigned all his football posts in June and FIFA banned Bin Hamman from the sport for life, a penalty he is contesting.

Blazer said he will retain his post on the FIFA executive committee. His term runs through mid-2013.
