Kenyan Asbel Kiprop has been banned from athletics for four years over doping.
The ban is effective May 2018, meanjng he has already served close to a year off the suspension period.
The former Olympic and World champion failed a drug test and was suspended for using performance-enhancing substances but he denied using any banned substances.
A out-of-competition test in Iten in November 2017 found that he had used banned blood booster Erythropoietin (EPO), leading to his suspension in May 2018.

He appealed against his suspension, his lawyer Katwa Kigen arguing that ‘A’ and ‘B’ samples had brought different results, which was basis for suspicion.
Kiprop, through Kigen, told the IAAF disciplinary committee that the Athletes Integrity Unit had declined DNA tests to verify that the samples were taken from Asbel.
The former African champion, who has recently courted controversy over his love triangle affair involving his fellow athlete, further cites violations of doping testing procedures.
He says, contrary to the norm of athletes informing anti-doping authorities of his whereabouts, he was informed of an impending test which is evidence of a pre-meditated outcome.
