Black Stars team doctor, Dr Martin Engmann yesterday joined other medical staff from world cup participating countries to endorse FIFA’s anti-doping campaign.

Engmann and thirty-one other team doctors have signed a declaration to fight doping in the sport.

Apart from consenting to doping controls, the medical staff have also received instructions on players' nutrition as an alternative to dietary supplements to avoid any problems with banned drugs.

Meanwhile specially trained FIFA doping doctors will be conducting random tests in matches leading up to the World Cup from March to June as well as in FIFA World Cup training camps.

Four players from each team will be tested under this initiative.
