Kenyan athlete and 10-km road race world record holder Rhonex Kipruto (23) has been provisionally suspended for an anti-doping violation, the Athletics Integrity Unit (AIU) said on Wednesday.
Kipruto, who also won a 10,000m bronze medal in the 2019 world championships, broke the 10-km road race world record in 2020.
The AIU said on Twitter that Kipruto had been suspended "for the use of a Prohibited Substance/Method (ABP)".
ABP refers to the Athlete Biological Passport, which shows discrepancies that can reveal the effects of doping.
