TULSA, Okla. — Former sprinter Marion Jones has signed on to play with the WNBA's Tulsa Shock, hoping to launch a new career after losing five Olympic medals for using performance-enhancing drugs.

Jones was a star at the 2000 Olympics in Sydney but admitted two years ago that she had taken a designer steroid known as the "clear." She was stripped of her medals, including three golds.

She also spent about six months in a Texas federal prison for lying about doping and her role in a check-fraud scam.

Before she became known as the world's fastest woman, Jones was the starting point guard on North Carolina's national championship team in 1994. She was drafted by Phoenix in 2003 but never played in the WNBA.

Jones was introduced Wednesday at a news conference in Tulsa.
