Former Sunderland striker Asamoah Gyan is among more than 40 players to have been found guilty of having “unethical hair” under United Arab Emirates Football Association guidelines. The 31-year-old Ghanaian is on loan at Dubai-based Arabian Gulf League side Al Ahli from Shanghai SIPG. In 2012, Saudi Arabia goalkeeper Waleed Abdullah was told to cut his “un-Islamic” hair by the referee before playing for his club side Al Shabab. The Saudi rule bans mohawk-style cuts. Some Islamic teachings ban ‘Qaza’ hairstyles, which include mohawks, because only part of the head is shaved, leaving other parts unshaven.
