Fred Kerley, the former world 100-meter champion, has been handed a two-year ban from competition for an anti-doping whereabouts violation.

Kerley won the world championship in the men's 100 meters at the 2022 World Athletics Championships in Eugene, Oregon. The American sprinter also claimed silver in the same event at the 2021 Tokyo Olympics.

Whereabouts violations occur when athletes fail to properly inform anti-doping authorities of their location for testing purposes. Under World Athletics anti-doping rules, athletes must provide accurate information about where they can be found for one hour each day to allow for unannounced drug testing.

The ban will prevent Kerley from competing in official track and field events during the suspension period. The timing of the ban could impact his ability to participate in major upcoming competitions, including the 2024 Paris Olympics and future world championships.

Kerley has been one of the world's top sprinters in recent years, consistently ranking among the fastest men in the 100-meter dash. His career achievements include multiple medals at major international competitions.
