Matthias Kessler is in an induced coma in hospital on the Spanish island of Majorca after suffering severe head injuries in a training crash.
The former Astana rider is understood to have fallen after his bicycle hit a cat during a training ride near Algaida, Mallorca on Wednesday with fellow German rider Andreas Klöden of Team Radioshack.
"Matthias Kessler suffered a severe cranial trauma and is in the intensive care unit in an induced coma," a spokesman for the Son Dureta hospital in the Majorcan capital of Palma told AFP. He added that the rider was in "serious condition" but "his life is not in danger".
Kessler, 30, turned pro with Team Telekom in 2000. He joined Team Astana along with Klöden in 2007. That spring Kessler tested positive for testosterone and was suspended for two years. His suspension ended in July 2009.
