United Arab Emirates Football Association (UAEFA) deemed more than 40 players to have 'unethical hair'.
Former Sunderland striker Asamoah Gyan, who now plays for Arabian Gulf League side Al Ahli from Shanghai SIPG in the country is also there on the list of players with 'Qaza' hairstyles, which is not allowed under some Islamic teachings.
The 31-year-old Ghanaian will have to rethink on his hairstyle before appearing for the team in the next match.
In UAE, individual match referees have the absolute freedom to decide upon whether players with ‘Qaza’ can take part in the club football match.
According to the sources, UAE made the restriction on hairstyles as there are chances of children copying football stars in the hair cut.
Meanwhile, UAE is not the only middle eastern country to have such guidelines for hair cuts. In 2012, Saudi Arabia had directed its goalkeeper Waleed Abdullah to cut his "un-Islamic" hair before playing for his club side Al Shabab.
The UAEFA usually sends letters to the players who violate hairstyles' law and will impose fines later on when they refuse to abide by the law.
Gyan was on the receiving end of the warning letter among 46 other players.
Middle Eastern football website Ahdaaf, Al Wahda's claimed that the UAE football authorities told player Suhail Al-Mansoori to cut his hair during UAE international, while the Arabian Gulf League player Omar Abdulrahman, who is with the same hairstyles that of Suhail's was let off.
