Strasbourg, France (AFP) - Jan Ullrich and Ivan Basso have been named in Spain's judicial investigation into blood doping, Cadena Ser radio station reported on Thursday. Both T-Mobile rider Ullrich of Germany and Italian Basso of CSC are hot, pre-race favorites for the July 1 to 23 Tour de France.

Other riders named include Spaniards Joseba Beloki, Roberto Heras, and Francisco Mancebo, American TylerHamilton and Colombian Santiago Botero, according to Cadena Ser.

The news was revealed after the judge in charge of the investigation lifted reporting restrictions on Thursday at the request of prosecutors.

Although the judge will be making no official statement, a judiciary source told AFP that "the leaks have come from lawyers."

Ullrich, however, represented by team spokesman Christian Frommert, on Thursday once again denied he had anything to do with the matter.

"We have again asked Jan and (T-Mobile teammate) Oscar (Sevilla) for an explanation," said Frommert. "They both maintain what they have already said, they have nothing to do with this affair."

And Tour de France organizers said they would wait for more information before commenting.

"We are waiting for information," a spokesman told AFP.

Following the raid, the managers of two Spanish teams, Manolo Saiz of Liberty Seguros-Würth (now Astaná-Würth) and Comunidad Valenciana's Ignacio Labarta, were arrested and subsequently resigned their posts.

The Comunidad team was kicked off the Tour de France and the new Astaná-Würth team, featuring Tour hopeful Alexandre Vinokourov of Kazakhstan, were asked not to participate.

That seemed to be about as far as the issue went until Spanish newspaper El País claimed Monday that documents found in the raid could relate to 1997 Tour de France champion Ullrich. Thursday’s release of additional documents appear add fuel to that fire.

The newspaper said two code names – “Hijo Rudicio” (Rudicio's son) and the none-too-subtle “Jan” - could be used to describe Ullrich, who has been the subject of Spanish press speculation over the blood-doping saga since the so-called Operación Puerto was launched on May 23.

El País claimed to have cracked the codes contained in documents pertaining to the dosages of blood-doping taken by clients of the laboratory.

"Some names were easy to decipher whereas others were more complicated," said El País. "According to the investigators, Rudicio was Rudy, Rudy Pevenage, the Belgian sports director who the past few years has become Jan Ullrich's sporting guru."
