The athlete had already two missed tests filed when the third happened on December 9, 2019. An athlete has to file their whereabouts and inform anti-doping authorities they are available for testing during a 60 minute time slot. On the date mentioned the athlete was out shopping and stayed out until the 60 minute time slot was over. The Doping Control Officer and a Blood Collection Assistant were waiting outside the athlete house for a good our. It was just after the DCO and the BCA at left the athlete returned to his residence.

In the decision papers it states that An athlete who is in a Registered Testing Pool (RTP) is required to make quarterly whereabouts filings that provide accurate and complete information about the Athlete's whereabouts during the forthcoming quarter, including identifying where he/she will be living, training and competing during that quarter, and to update those whereabout filings where necessary, so that he/she can be located for testing during that quarter at the times and locations specified in the relevant whereabouts filing.

During the month of October the Athletics Integrity Unit (AIU) has reported two Whereabouts failures where Coleman is one of the athletes sanctioned. The other athlete who has been involved in a Whereabout failures case is Salwa Eid Naser who represents Bahrain had one of her Whereabout failures disqualified.
Naser is being aided by an agent to update her Whereabouts information in ADAMS which is the tool athlete use to report their Whereabouts.

In the Anti-Doping Database we have more than 130 anti-doping rule violations related to Failing to provide Whereabouts information (rule 2.4). Russia currently has the most ADRVs registered with 22 followed by USA with 20 (we have not registered Coleman yet as he may appeal the decision). France and Portugal both have ten cases.
Track and Field has the most ADRVs for this rule with 33 followed by Swimming (12) and Wrestling (9). 53 athletes has been suspended for one year. 31 has been suspended for two years.
