United States sprinter Fred Kerley has been provisionally suspended for an alleged anti-doping whereabouts violation, the Athletics Integrity Unit (AIU) announced on Tuesday.

Kerley, 30, who won 100m bronze at last summer’s Paris Games, could face a two-year ban if the charge is upheld.

The World Anti-Doping Code states an athlete cannot miss three anti-doping tests and/or filing failures within a 12-month period.

In a statement posted on X,, external lawyers for Kerley said he intends to contest the allegation.

“[Kerley] strongly believes that one or more of his alleged missed tests should be set aside either because he was not negligent or because the doping control officer did not do what was reasonable under the circumstances to locate him at his designated location,” it added.
