The IAAF has this evening (26 August 2015) announced that two Kenyan athletes, Koki MANUNGA and Joyce ZAKARY, have accepted provisional suspensions following positive samples provided in Beijing on the 20th and 21st of August respectively.
The IAAF Rules dictate that the IAAF is only able to make a public disclosure once this provisional suspension is in place.
?Zakary ran 50.71 for the national record in the opening round of the 400m on Monday while Manunga, in the heats of the 400m hurdles on Sunday, finished sixth.
These targeted tests were conducted by the IAAF at the athlete hotels during the pre-competition phase. The IAAF will not discuss the details of the cases as they progress through the results management process.
