FORMER Harriers defender Chey Dunkley has admitted to breaching The FA’s anti-doping regulations for accidentally taking a banned substance in his asthma treatment.

Dunkley, who moved to Oxford from the Reds for £50,000 in January, failed a routine drug test at the U’s.

A regularity commission has ruled there was no intention to enhance his sporting performance.

He was issued with a warning and reprimanded, and will be subject to target testing for a period of two years.

A statement from Oxford said: “Chey suffers from asthma and was not aware of the restriction on salbutamol use. As a club, we accept the FA ruling.”
