Paris, France (My Sportsbook) - Seven-time Tour de France champion Lance Armstrong will not face disciplinary action after he was accused of violating anti-doping rules during a test following a training session in southern France last month.

The French anti-doping agency (AFLD) released a statement Friday, clearing Armstrong of any potential wrongdoing after issues were raised concerning a delay during a random test on March 17.

"The College of the AFLD has decided to take into account the written explanations from the athlete and therefore not to initiate disciplinary proceedings against him," the statement read. "Analysis of urine and blood samples of Mr. Lance Armstrong did not reveal any abnormality."

Earlier this month, the AFLD said Armstrong "did not meet the obligation to remain under direct observation of the person responsible for the control" of the test.

Armstrong, making a comeback after a 3 1/2-year retirement, had denied any wrongdoing from the March 17 test, during which time a 20-minute delay in the procedure was at issue.

"Just got the word from the French agency AFLD on the shower gate incident. Case closed, no penalty, all samples clean. Onward," Armstrong wrote on his web site Friday.

After a training session, a tester followed Armstrong back to his home and requested samples. Armstrong said he was granted permission by the tester to take a shower while Astana Team manager Johan Bruyneel confirmed the man's credentials.

The tests -- urine, blood and hair samples -- all came back negative.

Armstrong indicated that the forms he signed included a provision for the tester to state if there were any irregularities from the process and he wrote "no."

The laboratory, however, decided to investigate the 20-minute delay.

Armstrong won the first of his seven straight Tour de France crowns in 1999 and the last in 2005, announcing his retirement shortly after the final title.

The French newspaper, L'Equipe, reported in August 2005 that six of Armstrong's urine samples from 1999, tested in 2004, came back positive for EPO -- a hormone that increases red globules and allows a better muscular oxygenation.

In May of 2006, a Dutch lawyer in charge of investigating those allegations, cleared Armstrong of any wrongdoing.

Armstrong has always denied ever using performance-enhancing drugs.
