The father of Andy and Frank Schleck has said that he wants his sons to give up cycling.
The brothers both ride for the RadioShack Nissan-Trek team, but both missed the majority of the 2012 season.
Johny Schleck, who was also a professional cyclist, told Le Journal du Dimanche: "I advised them to quit cycling.
"Frank is depressed. He spent a lot of money on medical analysis and lawyers fees trying to prove his innocence. This is not a life."
The Luxembourg anti-doping agency heard Frank's case last week, and he faces a two year ban from cycling if found guilty.
