Former Sunderland forward Asamoah Gyan has been found guilty of having "unethical hair" under United Arab Emirates Football Association guidelines, according to a report by the BBC.

The 31-year-old is one of 46 players to have been found to have breached Arabian Gulf League rules on inappropriate hairstyles.

Arabian Gulf League referees are tasked with deciding whether a player's hairstyle is not in keeping with UAEFA guidelines.

Offending players are then sent a warning letter with threat of further action if the matter is not addressed.

Gyan is currently on loan at Arabian Gulf League side, Al Ahbi, who are based in Dubai.
