Sprint coach Trevor Graham could face up to 15 years in jail after being charged with hindering a US government investigation into steroids in sport. Graham, whose stars included disgraced Olympic 100m champion Justin Gatlin, was indicted on three counts of making false statements to federal agents.
He has been summoned to appear in court for arraignment on 16 November.
If convicted of all three counts, Graham could face a maximum penalty of 15 years in prison and a $750,000 fine.
