The executive board of the Nigeria Football Federation (NFF) on Thursday dismissed president Aminu Maigari after he was impeached for misuse of funds.
Vice-president Mike Umeh will serve as acting president.
A statement from the executive committee meeting said that "after thorough and exhaustive deliberations" on the secretive nature of the federation's financial dealings and a "failure to call a meeting of the executive committee for the past eight months" during which time many important decision were made, the board had passed a vote of no-confidence on Maigari.
It therefore approved his immediate dismissal from the NFF executive committee on grounds of financial misappropriation, misapplication and maladministration.
Umeh will preside over the affairs of the federation pending the composition of the new NFF executive committee after the elections on August 26.
It is believed that eight of 13 executive committee members signed the impeachment motion.
