Pevenage (background) with Oscar Sevilla and Jan Ullrich

Ullrich and team-mate Oscar Sevilla were among 13 riders withdrawn from the Tour de France before the race.

Both riders, along with Belgian Pevenage, were suspended by T-Mobile.

"The contract linking T-Mobile to Pevenage has been retrospectively stopped on 30 June," the team's general manager, Olaf Ludwig, said on Sunday.

The team has yet to make a decision over Ullrich and Sevilla, who were among 56 riders listed by the Spanish investigation.

Neither rider has failed a dope test, and they deny any wrongdoing, but both were withdrawn as part of an anti-doping agreement between teams competing at the Tour de France.

According to Spanish police files, Pevenage, 51, was a client of cycling doctor Eufemiano Fuentes, who allegedly provided an illegal blood-boosting service and doping products to athletes.

The Belgian has advised Ullrich since the beginning of his professional career, overseeing his 1997 Tour victory while sporting director of T-Mobile forerunner, Team Telekom.

But Pevenage fell out with team manager Walter Godefroot when Ullrich left in 2002 after being convicted of amphetamines and drink-driving offences.

Ullrich was re-admitted to T-Mobile in 2004 but, although his mentor was tolerated as a "personal adviser" by team management, he was not allowed into the team's inner circle.
