Olympic gold medalist Tim Montgomery was sentenced to almost four years in prison Friday for his part in a fake-check scheme.

Montgomery hung his head as Judge Kenneth Karas imposed the sentence of 46 months.

The 33-year-old former track star pleaded guilty last year to conspiracy in a multimillion-dollar bank fraud and money laundering plot. Prosecutors said 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 who is now in prison for lying about the check scam and about her use of performance-enhancing drugs.
