On 17 August 2015, the Court of Arbitration for Sport says it approved a settlement agreed to by Turkish athlete Aslı Çakır Alptekin and the IAAF. Alptekin has agreed to forfeit her 1500 metres Olympic title and serve an eight-year ban for blood doping. On 29 March 2017, Turkish athlete Gamze Bulut was banned for doping and lost her Olympic silver medal. Maryam Yusuf Jamal of Bahrain was advanced to gold. In the case of silver and bronze medals reallocation the silver medal could be awarded to Tatyana Tomashova of Russia, and the bronze medal could be awarded to Abeba Aregawi of Ethiopia. However when reallocating medals, the IOC has previously elected not to advance athletes with a history of doping violations. Both Tatyana Tomashova and Abeba Aregawi had doping violations in the past. Therefore, it is possible that runners from the United States (Shannon Rowbury) and Slovakia (Lucia Klocová) in the original sixth and seventh positions could be awarded medals.
