The Athletics Integrity Unit (AIU) has banned Elijah Manangoi for two years for "whereabouts failures", which is a breach of World Athletics anti-doping regulations.

The 27-year-old is now set to miss the 2020 Olympic Games in Tokyo, having missed three doping tests.

Manangoi was provisionally suspended in July for the violations and the AIU said his ban will come into effect "on the date of the third Whereabouts Failure" from Dec. 22 2019.

The ruling means "disqualification of all competitive results obtained by the athlete since 22 December 2019 with all resulting consequences, including the forfeiture of any titles, awards, medals, points prizes and appearance money," AIU said in the statement.

Manangoi is the latest in a series of high-profile Kenyan athletes to be banned for violatins of anti-doping regulations.

Others who has been banned include 2008 Olympic 1,500m champion Asbel Kiprop, former Boston and Chicago Marathon winner Rita Jeptoo and 2016 Olympic marathon champion Jemimah Sumgong.
