Marathoner Lawrence Cherono, who was set to represent Kenya in the World Athletics Championships Oregon22 on Sunday has been provisionally suspended by the Athletics Integrity Unit (AIU) over use of a prohibited substance in an out-of-competition test on May 23, according to the AIU. 

AIU submitted that a sample collected from Lawrence Cherono tested positive for trimetazidine, a substance that is prohibited under the 2022 WADA Prohibited List as a metabolic modulator.

"Trimetazidine is a non-specified substance and a provisional suspension is mandatory following an adverse analytical finding for such a substance under the World Athletics Anti-Doping Rules unless certain conditions apply," AIU said in a statement.
