NEW YORK: American sprinter Deajah Stevens, who reached the 2016 Rio Olympics 200 metres final, has been provisionally suspended for failing to make herself available for anti-doping tests, the Athletics Integrity Unit (AIU) said on Friday. Stevens cumulated three whereabouts violations over a 12-month period, the AIU said in a statement. The 24-year-old won the U.S. 200m title a year after finishing seventh in the Olympics final. Her 23-year-old compatriot Gabrielle Thomas, twice a 200m winner at the Lausanne Diamond League, was also provisionally suspended for three whereabouts violations, the AIU said. Kenyan Alex Korio Oliotiptip, who took part in last year’s INEOS 1:59 challenge which saw compatriot Eliud Kipchoge became the first person to run a marathon in under two hours, was also suspended for three whereabouts violations. All three athletes could face a two-year ban. Mikel Kiprotich Mutai of Kenya, who won the Hong Kong marathon in 2016, was provisionally suspended for failing a test for the banned substance norandrosterone, the AIU added.
