Olympic hurdles champion Brianna Rollins-McNeal has been provisionally suspended for a doping rules violation, the Athletics Integrity Unit said Thursday. Rollins-McNeal won gold in the 100-meter hurdles at the 2016 Rio de Janeiro Olympics. The 29-year-old American was also world champion in 2013.
The AIU said it charged Rollins-McNeal with tampering within the results management process, but did not specify details of the case.
The AIU cited a section in the World Anti-Doping Code that covers conduct which subverts the doping control process.
The code gives one example as altering identification numbers on a doping control form during testing.
Rollins-McNeal is the fourth fastest woman in history in her event. She clocked 12.26 seconds at the U.S. national championships.
