BRUSSELS, Belgium -- With only one week to go before the Beijing Olympics, Russia suddenly has its own version of a BALCO doping scandal involving some of the track team's biggest stars.

After a 1 1/2-year investigation, the IAAF provisionally suspended seven female Russian athletes Thursday, accusing them of tampering with their urine samples. The list includes Yelena Soboleva, a world record-holder and world champion middle-distance runner who was favored to win both the 800 and 1,500 meters at the Olympics.
