Ghana's football star Asamoah Gyan has been given a new title after he was stripped of the team captain role for the national team.
Black Stars coach, Kwasi Appiah, named Gyan "general captain", because of his seniority in the team.
Andre Ayew was named the new permanent captain.
Coach Appiah’s decision follows a meeting with the top management team of the Ghana Football Association Normalisation Committee.
On Monday, Gyan announced his retirement from the national team to protest against plans to replace him as captain.
He rescinded his decision after a telephone conversation with President Nana Akuffo-Addo.
Before his replacement, Gyan had been the Black Stars' captain for seven years and had scored 51 goals for the team.
The captaincy controversy has been a problem for the Ghanaian national football team for many years.
The Black Stars will play their opening Africa Cup of Nations match against Benin on 25 June.
They have not won the tournament since 1982.

Police in Algeria have been carrying out a major operation to try to limit the latest Friday mass protest demanding comprehensive political reform.
Witnesses say that there have been a larger number of arrests than usual and a heavier police presence in the capital, Algiers.
This is the fourteenth consecutive Friday that Algerians have taken to the streets calling for the country's leaders to resign.
The protest movement forced the veteran president, Abdelaziz Bouteflika, to stand down last month - some of his closest aides are now facing trial.
The authorities are planning to hold a presidential election on 4 July.

Uganda has been on high alert because of the outbreak of the haemorrhagic fever in eastern Congo, just across the border from Kagadi where the victims died.
On Thursday the United Nations warned the risk of Ebola spreading to neighbouring countries was very high.
