Astana's Andriy Kashechkin has tested positive for a homologous blood transfusion at an out of competition control in Turkey on August 1.

The 27-year-old Kazakh is the third member of his team to fail a dope test this season, after Matthias Kessler was found to have an abnormally high level of testosterone a day before the Fleche Wallonne, and Alexandre Vinokourov tested positive for a transfusion after the first time-trial of the Tour de France.

He has been suspended by the team following the result of the 'B' test.

Astana last week announced their decision to pull out of all racing while they redevelop their code of ethics and put in place "new draconian measures" to help prevent a repeat of the scandals that have blighted their name.

"While Astana is doing everything to take a fresh start on new foundations, Kashechkin's positive test once again questions the credibility of the team," Astana said.

"This new blow just reinforces the will of Astana Cycling Team to set up drastic measures for clean cycling."

They were not invited to the Deutschland Tour, though are expected to be in Vigo for the start of the Vuelta a Espana in September.
