     BRISBANE-Australian Olympic chief John Coates has said Greek athlete Katerina Thanou should

not be awarded the Sydney Olympics 100 metres gold medal handed back by Marion Jones.

     Jones, who this week admitted to steroid(类固醇)use in the build up to the Sydney Games, has

returned the three gold medals and two bronzes she won in 2000.

    But Thanou, the silver medalist in Sydney, was herself banned for two years after she failed to appear

for a drug test at the 2004 Athens Olympics.

     "I'd like to think that Katerina Thanou would not be awarded the gold medal," Coates told the

Australian Associated Press on Tuesday, "but there may be some legal difficulties for the International

Olympic Committee (IOC) to overcome in order to reach that conclusion."

     Jamaica's Tayna Lawrence won the 100m bronze medal in Sydney behind Jones and Thanou.

Coates also said he expected the United States Olympic Committee (USOC) to hand back the medals

won by the women's 4x100m and 4x400m relay teams.

     Two of Jones's team mates in the 4x100m team which finished third in Sydney, Torri Edwards and

Chryste Gaines, have also served doping(兴奋剂)bans.

     The U.S. women's 4x100m relay team won the gold medal ahead of Jamaica and Russia.

     "On the relays, it's my expectation that the United States Olympic Committee will be required to also

hand back the medals won by the other ladies who competed with Jones in the two relays," Coates said.

     "That is normal practice."

     The United States Olympic Committee (USCO) has publicly apologized to the organizers and

competitors of the 2000 Sydney Games and the Australian public for Jones's actions.

    As part of the USOC's apology, president Peter Ueberroth promised that the U.S. would send a clean

team to next year's Beijing Olympics.
