WASHINGTON, April 20 (Xinhua) -- American Olympic champion hurdler Brianna Rollins has accepted a one-year ban for failing to report correctly her whereabouts to anti-doping officials.

Rollins missed three tests, on April 27, Sept. 13, and Sept. 27 which resulted in an anti-doping violation. The ban is retroactive to Sept. 27, 2016, the date of her last missed whereabouts report, which will not affect her 100m victory at the Rio Olympics but keep her out of this year's world championships in London in August.

In a news release 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.
