Kamila Valieva positive test 'due to grandfather mix up', IOC defends response to doping case
Kamila Valieva’s defence surrounding her positive test for trimetazidine was due to a mix up with her grandfather’s heart medication, Denis Oswald, Permanent Chair of the International Olympic Committee's Disciplinary Commission, said at the joint IOC & Beijing 2022 daily briefing on Tuesday. That argument was made at her hearing with the Court of Arbitration for Sport (CAS) on whether she should be able to compete at Beijing 2022 Winter Olympic Games, Oswald said.
