The Athletics Integrity Unit announced on Friday the suspension of Jamaican athlete Christopher Taylor for 30 months due to a violation of anti-doping rules. The Integrity Unit stated that "Taylor, who helped Jamaica win the silver medal in the 4x400 meters relay at the 2022 World Championships, failed to comply with the sample collection process during an out-of-competition test nearly a year ago." The suspension will start from the date of the offense, and Taylor will be eligible to return in May 2025.
