According toReuters, the 33-year-old tested positive for erythropoietin (EPO) during the Manchester Great Race in May 2022, a banned substance that boosts the production of red blood cells, providing an unfair advantage in endurance events.
The outlet said that Robertson received a four-year ban for testing positive and a second four-year ban for tampering with evidence.
PerCNN, Robertson claimed that he visited a medical facility in Kenya to receive a COVID-19 vaccine but instead received treatment for the infection, which he said is when he was administered EPO.
The athlete provided testimonies from Kenyan doctors, hospital records and a witness statement from a detective to attempt to show he did not take EPO intentionally.

But the organization Drug Free Sport New Zealand (DFSNZ) showed evidence from the vice president of the medical center Robertson said he attended, who said he was not administered EPO at the facility and did not visit it on the date he claimed.
DFSNZ also said that Robertson may have presented falsified documents and false testimony, the judgment said.
PEOPLE reached out to Robertson for comment on Wednesday afternoon.
He was credited for time served under provisional suspension but is still barred from competitive sports until September 2030.
