Australian Olympic swimmer Jarrod Poort has been banned for 12 months for failing to make himself available for doping tests, officials said Thursday. Poort, who swam in the 1500m at the 2012 London Olympics but switched to the open water events at Rio last year, waived his right to appeal. "At the end of the day people make mistakes and that's what I did," said Poort, who won hearts with a gutsy effort in the 10km open water race in Rio, leading the

first 9km before being on the final lap to finish 20th. "It was remiss of me to neglect a management system that must be shown the full respect it deserves and it is a very embarrassing situation to now be in." Under anti-doping rules, athletes are required to keep authorities informed about their location for one hour every day so they can be quickly found for out-of-competition testing.
