The IAAF suspended Moroccan runner Mariem Alaoui Selsouli from the London Olympics on Wednesday after she tested positive for doping.
The governing body said Selsouli tested positive for the diuretic furosemide at the Paris Diamond League meeting on July 6.
Selsouli became an Olympic medal favorite after clocking 3 minutes 56.15 seconds in the 1,500 meters - more than four seconds below her personal best time - in Paris.
''Selsouli has waived her right to the B (backup sample) analysis, and as a result has now been provisionally suspended from all competition in athletics,'' the IAAF said in a statement.
She ''still has the right to request a hearing which needs to be held by the Moroccan Athletic Federation within the next three months. Until such time, the IAAF will make no further comment on this case,'' the governing body said.
The 28-year-old runner faces a lifetime ban if the second doping offense of her career is proven. Selsouli finished serving a two-year ban last August for using EPO before the 2009 world championships.
Furosemide is included on the World Anti-Doping Agency list of prohibited substances. It can also be used as a masking agent to disguise the presence of other performance-enhancing drugs.
