American Olympic champion hurdler Brianna Rollins has accepted a one-year ban for failing to report correctly her whereabouts to anti-doping officials, a media report said.
Rollins missed three tests, on April 27, September 13, and September 27 in 2016, which resulted in an anti-doping violation, Xinhua news agency reported.
The ban is retroactive to September 27, the date of her last missed whereabouts report, which will not affect her 100m victory at the Rio Olympics.
However, it will keep her out of the 2017 world championships in London in August.
In a statement released on Thursday, her attorneys said the computer program mix-up caused the ban as it listed her location on certain dates as both her home and a track meet where she was competing.
