San Antonio, TX -- (Sports Network) - Disgraced former Olympic track and field star Marion Jones was released from a federal prison in Texas Friday after serving a six-month sentence.

Jones was sentenced to the six-month term for lying to federal prosecutors about her steroid use and her knowledge of a check-fraud scam involving her ex-boyfriend, former sprinter Tim Montgomery.

The sentence completed a fall from grace for Jones, who was once regarded as one of the greatest female athletes in the world.

In the past, Jones denied the use of any steroids, including to federal prosecutors when questioned in 2003. However, she finally admitted last October, in an emotional and tearful public statement to her family, friends, and fans, to using the steroid "the clear," produced by the Bay Area Laboratory Co-Operative -- also known as BALCO -- that was given to her by her trainer Trevor Graham.

Jones admitted to taking the steroids leading up the 2000 Summer Olympics in Sydney, Australia. Jones was named Athlete of the Year by several organizations in 2000 for her accomplishments at the Sydney Games, where she became the only female track and field athlete to win five medals -- three of them gold -- at a single Olympics. She has been stripped of all of those medals as a result of her admitted steroid use.
