BRIVE LA GAILLARDE, France - Frank Schleck's B sample has also come back positive for a banned diuretic, the RadioShack-Nissan rider said on Friday.

“Today I witnessed the analysis of the B-sample. The result of the counter test was positive but for me nothing changes: I just know that I did nothing wrong,” Luxembourg's Schleck, pulled out of the Tour de France by his team after it was announced he had failed the A test, said in a statement.

“I will therefore continue my search to find out how the substance could have entered my body.” – Reuters
