Olympic gold medalist Tim Montgomery has been sentenced to 46 months in prison for his part in a fake-check scheme.

The sprinter hung his head as a judge imposed the sentence Friday in White Plains, N.Y.

The 33-year-old former track star pleaded guilty last year to conspiracy in a multimillion-dollar bank fraud and money laundering plot. Prosecutors say he had a hand in depositing bogus checks worth $1.7 million.

Montgomery retired in 2005 after he was banned from track and field for doping.

He has a child with Marion Jones, the track superstar serving prison time for lying about the check scam and about her use of performance-enhancing drugs.

Montgomery still faces drug-dealing charges in Virginia.
