Former sprinter Marion Jones has signed 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 Sydney Olympics but admitted two years ago that she had taken 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 the University of North Carolina's national championship team in 1994. She was drafted by Phoenix in 2003 but never played in the WNBA.
