The world of athletics has been rocked by the revelations that two of the best sprinters in the world have both failed drugs test for banned substances, and look set to face lengthy bans.
Neither Tyson Gay or Asafa Powell will now take part in the World Athletics Championships next month in Moscow.
Gay is the joint second fastest man to run 100m in a time of 9.69 seconds, while Powell is the fourth fastest at 9.72 seconds.
Gay who failed his drugs test in an out of competition test during May has already admitted his guilt, before the B test is returned.
Gay told Sports Illustrated: "I don't have a sabotage story. I don't have any lies. I don't have anything to say to make this seem like it was a mistake or it was on USADA's hands.
"I don't have any of these stories I basically put my trust in someone who let me down."
In comparison Powell has denied his guilt after he failed a drugs test in June at the Jamaican Championships.
Powell released a statement saying: "I want to be clear in saying to my family, friends and, most of all, my fans worldwide that I have never knowingly or wilfully taken any supplements or substances that break any rules, "I am not now - nor have I ever been - a cheat."
Powell will be hoping that the B sample backs up his claim following the adverse findings from the A sample taken in competition.
Following on from this jaw-dropping news, Sky News are reporting that five Jamaican athletes have failed drugs tests - including Powell.
They quote the chairman of the Jamaican Anti-Doping commission as confirming, 'reports of adverse analytical findings from A samples'.
However he wouldn't reveal the names of these athletes until they had been informed of the failing of the A samples.
This Sunday will go down as one of the days that two heavyweights in the sprinting world have been knocked out.
It remains to be seen how athletics and sprinting will pick themselves up from this with two of the best and fastest sprinters failing drugs tests, serious questions will begin to be asked about the sport and it's future.
