Olympic gold medallist Gil Roberts has been cleared of any wrongdoing and will not face a ban after an arbitrator from the American Arbitration Association (AAA) ruled he had not deliberately taken a banned substance.
Roberts, a member of the United States team which won the men's 4x400 metres relay title at last year's Olympic Games in Rio de Janeiro, tested positive for probenecid, a diuretic and masking agent, in an out-of-competition test in March.
However, the AAA has ruled that the 28-year-old from Oklahoma had "ingested a prohibited substance without fault or negligence".
