In the 9th stage of the Tour de France 2011 Vinokourov fell and broke his right femur. On 17 July 2011, his "retirement" from professional cycling was announced, unofficially and without comment, on Twitter pages by fellow cyclists. Later that day he confirmed his retirement. Rehabilitating from the accident he discovered he felt better than he had anticipated, and decided to ride the 2011 Giro di Lombardia before retiring. In September, he decided to postpone his retirement altogether, and announced he would return for the 2012 season and ride for Astana in the Tour de France.
