Brief updates:
Marion Jones, the two-time defending World Cup champion, decided to bring an end to her season, and passed on her team spot in the 100 meters. She will be replaced by Torri Edwards (photo), who displayed her strong late season form with her 11.06 runner-up finish at last weekend's World Athletics Final, where she finished second.

Notable doubles:
Saif Saaeed Shaheen will end his summer season with a difficult 5000/steeplechase double. In the 5000, he's set to face Kenenisa Bekele, and in the steeplechase, he'll take on Kenyan Paul Kipsiele Koech, currently the event's No. 2.

Sanya Richards, the world's dominant force in the 400, will also contest the 200. In the latter, she lowered her personal best to 22.17 last weekend at the World Athletics Final, where she finished second to Allyson Felix.
