FIFA has filed an appeal at the Court of Arbitration for Sport (CAS) as it seeks to increase a 15-match doping ban imposed by the Korea Football Association (KFA) on Kang Soo-il to two years.

Kang accepted his suspension in June of last year, blaming his positive test for banned steroid methyltestosterone on a moustache-growing cream he received as a gift.

The positive test was announced just hours before he was due to make his debut for South Korea in a friendly against the United Arab Emirates.

Kang was immediately withdrawn from the squad and returned to Seoul.

The CAS says FIFA's appeal against the KFA and Kang will be heard at its alternative hearing centre in the Chinese city of Shanghai on Friday (February 5).

The panel in charge of the matter comprises Portugal’s Rui Botica Santos, Israel’s Efraim Barak and The Netherlands’ Peter Van Minnen, who will hear the parties' arguments.

"The panel will then deliberate before issuing an Arbitral Award containing its decision at a later date," added a CAS statement.

The CAS typically delivers verdicts within weeks.

Kang is a 28-year-old forward currently playing for Jeju United in the K League Classic, South Korea’s highest and most prestigious level of football competition.

He had the option, as all players do, of requesting an examination of a B sample in a bid to clear his name, but instead decided to accept his suspension.

Kang was the second South Korean sporting star to be banned for a positive test last year after former Olympic swimming champion Park Tae-Hwan.

The International Swimming Federation Doping Panel backdated Park's 18-month suspension to September 3, 2014, the date on which Park provided the positive sample for testosterone, meaning he will be eligible to return to action from March 3, 2016.
