No sooner had the IAAF unveiled Maurice Greene as one of its worldwide ambassadors than the Olympic 100 metres champion and former world record holder was alleged by a witness in a forthcoming trial to have paid for performance-enhancing drugs.
You can imagine the sense of frustration at IAAF headquarters in Monaco.
Having done their best to erase all trace of Marion Jones from the record books following her admission of drug taking and subsequent jailing, only weeks later the sport's world governing body have had to field questions from around the world on what lies at the heart of the Greene allegations.
It is claimed that Greene, 33, who retired at the start of the year, has been named among 12 athletes - who between them have won 26 Olympic and 21 World Championship medals - who were supplied with performance-enhancing drugs by Angel Guillermo Heredia, a former discus thrower from Mexico.
Heredia is a prosecution witness in the federal trial in the United States next month of Trevor Graham, Jones' former coach, who has been indicted for lying to investigators about his part in supplying drugs.
Heredia's allegations include that Greene paid him around $40,000 (£20,000) for drugs, including steroids and stimulants, insulin and EPO in 2003 and 2004.
Greene denied the allegations and told The Daily Telegraph on the telephone from his home that he feared being smeared by them.
Normally, athletes faced with similar allegations either slam the phone down, deny all knowledge of everything or refer inquiries to their agent.
Greene did none of those. Not only did he take the time to read up on the allegations originally published in The New York Times, he spent 25 minutes outlining his reaction.
He said: "It's embarrassing. My name is smeared in stuff that's going to make me look bad and ruin my name.
"I met him [Heredia] before and when he was talking to me, I told him I don't believe in this stuff. I met with a lot of people who wanted me to try this and that. Everyone wanted me.
"But me getting anything or doing anything? I have not. My stance has always been that there's no place in our sport for drug users. I've always said it's a ban for life if you come up positive. I stand by that."
The one-time 'Kansas Cannonball' did add that he often paid for "stuff" for other athletes in his tight-knit training group.
If things looked messy for Greene then, they worsened when further allegations emerged that a letter had been written to him and his coach, John Smith, accusing them of lying about competing clean.
The author of the letter? It has been alleged that it was none other than Ato Boldon, the Trinidad and Tobago sprinter who was Greene's former training partner and the 100m silver medallist behind him in Sydney.
Boldon has not admitted writing the letter.
Emanuel Hudson, who still represents Greene and Boldon at HSInternational, said: "My understanding is that Ato says he has not written any letters."
Greene defied convention of avoiding the media for a second time, however, when he and Smith attended last weekend's Mt Sac Relays in San Antonio, California.
Greene refused to answer questions but was quoted as saying that he would tell his side of this story "soon" and "you'll understand when you hear about it."
The IAAF has asked for Greene to explain himself fully.
Confused by the emergence of a letter, whose author has not been confirmed, the IAAF would welcome enlightenment from Boldon, who, having retired in 2004, works with US television and became a senator in the Trinidad and Tobago Parliament. A spokesman said: "Ato Boldon is welcome to contact us."
Not surprisingly, the IAAF would rather not have to deal with the issues.
After all, it was five long years ago that the Balco doping scandal erupted, a host of top athletes were banned, Jones is in jail, records have been expunged and the drug testing has been intensified.
Surely the time has come for the focus to be upon the Olympic summer ahead and the performances we can look forward to on the track?
Try as it might to turn attention away from the doping problem, many believe the IAAF will have to confront the ugly truth that the Olympics and those performances are undermined by the rumours that continue to chip away at the sport's credibility.
The IAAF prefer not to deal in rumours. There are always plenty of those.
Instead, it will wait to see what facts and whose names emerge from the Trevor Graham trial, which is due to open in San Francisco on May 19.
The fear is that the case will make the dark clouds hanging over the sport darker still.
