Sprinter Mark Otieno and two marathoners were on Monday banned from competing for up to three years, the Athletics Integrity Unit (AIU) said, adding to the long list of Kenyans sanctioned for breaching anti-doping rules.
Otieno tested positive for the banned anabolic steroid methasterone and was suspended from the Tokyo Olympics in 2021 moments before he was due to compete in the 100m heats.
The 29-year-old will serve a two-year ban starting July 2021, the AIU said.
Marathoners Alice Jepkemboi Kimutai and Johnstone Kibet Maiyo were both banned for three years.
