New York, NY (AHN) - The world's fastest woman may finally be slowing down.

American sprinter Marion Jones, once the fastest woman on the planet, may not compete in the 2007 track and field season according to her agent, Steve Riddick.

"I'm almost sure she isn't," Riddick said in a telephone interview with The Associated Press on Friday.

Jones, the defending U.S. 100-meter champion, has not declared entry in that event or any other competition at next week's U.S. championships in Indianapolis.

Jones has been "off the grid" since marrying Barbados-born sprinter Obadele Thompson in a small ceremony near Raleigh, N.C., on Feb. 27.

Jones, who has battled accusations of illegal doping the last couple of years, is the only woman to ever win five track and field medals in a single Olympics.

Jones claimed her 14th U.S. title last season in the face of unwavering speculation about her alleged use of illegal performance-enhancing substances.

Jones' "A" sample tested positive for the banned endurance-enhancer EPO at the U.S. meet, but she was cleared of any guilt when her "B" sample came back negative.

While many of Jones' compatriots have been found guilty of illegal activities or are currently being investigated for such activities, including the father of her child sprinter Tim Montgomery as well as her former coach Trevor Graham, Jones has never has tested positive for a banned substance, other than the EPO sample that was later found to be wrong.

After taking the 2003 season off for the birth of her son, Jones bounced back in a big way last year, running her first sub-11 second 100 since 2002 before highlighting her year to an adoring crowd in Indianapolis.
