France winner Jan Ullrich in a Spanish blood doping scandal. "The contract linking T-Mobile to Pevenage has been retrospectively stopped on June 30", the team's general manager, Olaf Ludwig, said. On July 21, 2006, T-Mobile fired Jan Ullrich from the team pending the doping investigation. At the 2006 Tour de France, T-Mobile won the team classification for the third consecutive year, Andreas Klöden reached the podium (3rd place) for the second time, Matthias Kessler won Stage 3, Serhiy Honchar won two individual time trials (Stages 7 and 19) and wore the yellow jersey for 3 days (after Stages 7–9). After the Tour de France, the team changed significantly; team manager, Olaf Ludwig left the team and was replaced by Bob Stapleton. Rolf Aldag, Allan Peiper and Tristan Hoffman became directeur sportifs. As already discussed Ullrich, Sevilla and Pevenage were dismissed from the team. Several riders who had been with the team for a long time such as Steffen Wesemann, Andreas Klöden and Matthias Kessler left. However, the reason is unclear. Jörg Ludewig was put on suspension and his contract was not increased in connection with intention to dope previously in his career and before he joined T-Mobile. Eddy Mazzoleni who was in his first year for the team also left. The contracts of Bram Schmitz and Bas Giling were not renewed. Dr. Lothar Heinrich, the team doctor since 1995, and Dr. Andreas Schmid set up a new comprehensive testing system. Following the revelations that came out of the Operación Puerto investigation, Heinrich allegedly nearly quit the sport but instead he joined with Stapleton and other team staff to create a new system of internal controls and health checks that he insisted would demonstrate that T-Mobile riders were clean and to restore credibility to the sport. In May 2007, several former riders admitted to using banned substances (including EPO) while riding for the team in the mid-1990s, including Erik Zabel, Rolf Aldag, Brian Holm, Bjarne Riis, Bert Dietz, Udo Bölts and Christian Henn including the seasons in which Riis and Ullrich won the Tour de France. Team doctors Andreas Schmid and Lothar Heinrich also confessed to participating and administering banned substances. The latter was Team Telekom's sporting director until May 3, 2007, when he was suspended following allegations published in former team member Jef d'Hont's book. Jef d'Hont had worked as a massage therapist for Team Telekom in 1992–96, and revealed
