The Discovery Channel team issued a statement that said that the team "has requested that Italian rider Ivan Basso not compete pending further information in a new investigation coming out of Italy."
"We continue to stand behind Ivan and intend to cooperate with all parties involved until there is closure. It is unfortunate that this is now occurring, however, I have spoke to Ivan and although frustrated he agrees and understands with the decision we have taken," said director Johan Bruyneel.
According to the article, the case against Basso has been reopened as of today, by the Italian Olympic Committee (CONI) and to be pursued by an individual prosecutor.
And here's the Discovery Channel statement.
