The world football governing body, also handed down the same punishment to four other officials, who were involved in the Nigeria Football Federation (NFF) leadership tussle.
They are: Muazu Suleyman, Yahaya Adama, Sani Fema and Johnson Effiong.
“In accordance with art. 136ff of the FIFA Disciplinary Code, the chairman of the FIFA Disciplinary Committee has decided to extend the five-year ban from taking part in any kind of football-related activity imposed on the five officials to have worldwide effect,” a statement from FIFA read.
Giwa was first banned by the NFF in May 2016, after they approached a civil court over the leadership tussle – an action that is against the federation's statutes.
This five-year sanction was later extended by the Confederation of African Football (CAF).
