Former Sunderland striker Asamoah Gyan found guilty of having 'un-ethical hair'

Gyan, who spent two years at the Stadium of Light between 2010 and 2012, was one of 40 players found to be in breach of national rules on 'un-Islamic' hair cuts.

The Ghana international is currently on loan at Dubai-based Arabian Gulf League side Al Ahbi.

The haircut in question, which he sported at the recent Africa Cup of Nations, where his nation reached the semi-finals of the competition, is the latest version of his usual mohawk.

Should Gyan, or one of the 39 other players in breach of rules, be told cut their hair they would not be the first. There is a precedent for this kind of thing in the Middle East.

Suhail Al-Mansoori of Al Wahda was recently told to cut his curly perm.

Also in 2012 Saudi Arabia international goalkeeper Waleed Abdullah was forced to go for a trim.

Gyan is currently on a season-long loan from Shangahi SIPG in China.

He was linked with a switch to Reading in the last transfer window.
