FIFA says Abourazzouk's ban from all football runs through Feb. 27.
The 27-year-old Raja Casablanca player will miss the Club World Cup which is in Morocco in December. Raja Casablanca qualified as the league winner of the host nation.
Abourazzouk failed a doping control after Morocco's 2-1 win against Tanzania in Marrakech on June 8. He was an unused substitute.
Morocco is already eliminated from World Cup qualification.
