FIFA has agreed to adopt the World Anti-Doping Agency's revised drug-testing code.
FIFA president Sepp Blatter met Friday with WADA chief John Fahey in Zurich and signed a letter of intent to adopt the code.
Blatter says both organizations share a common objective of fighting doping and will do so "through all possible means."
The code takes effect Jan. 1. 2009 and is expected to be ratified in full at the FIFA congress in May in Sydney, Australia. Fahey will be a guest at the meeting.
FIFA says it is happy with the inclusion of more flexibility on doping sanctions in the code.
