Clément Venturini, who fell during the fourth stage of the Critérium du Dauphiné and was forced to abandon the race, has suffered a serious injury to his right knee that requires assessment and treatment in the operating theatre. This will take place on Thursday evening at the Valence Hospital Centre (Drôme), said Dr Eric Bouvat, medical director of the AG2R CITROËN team. The length of his absence will be specified at a later date.
