Nigeria have been given until Friday to avoid a "lengthy suspension" from football, FIFA has warned.
After months of uncertainty, Amaju Pinnick was elected as president of the Nigerian Football Federation (NFF) on Sept. 30, with FIFA confirming its recognition of the elections on Oct. 2.
However, a group led by Chris Giwa has taken the matter to court -- despite statutes forbidding football issues to be deliberated in a civil court -- as he alleges he was elected NFF president on Aug. 26.
FIFA secretary general Jerome Valcke has urged the NFF -- which has appealed the court ruling, with that appeal to be heard on Wednesday in Jos -- to resolve the situation or face a suspension.
"This gives Nigerian football a last opportunity to avoid a lengthy suspension," Valcke wrote in a letter to Pinnick.
"We inform you that if by Friday, Oct. 31, 2014, at midday Nigerian time we have not received proof that the case [the Jos Federal High Court ruling that sacked the Pinnick led NFF board] has been definitively withdrawn from court and that the board elected on Sept. 30, 2014, is able to carry out its activities without any hindrance, we will refer the case to the FIFA Emergency Committee for implementation of the suspension."
