From CyclingNews.com:

The organisers of the Vuelta a España, Unipublic, have stated that Jan Ullrich, Ivan Basso and Francisco Mancebo are not welcome in their event, which begins on August 26. This follows Unipublic’s decision to exclude Comunidad Valenciana on the basis of its involvement in the Operación Puerto affair. “We are taking this decision for the sake of the sport,” said a Unipublic spokesperson.

This comes before anyone has been tried in anything but the press. When and how will it end?
