The Italian is expected to miss three weeks of training after he was hit from behind and collided with a wall near his home in Monaco. Conti was training alone at the time and was discovered by a passing cyclist, who alerted emergency services.
"X-rays at the hospital in Nice showed a second-degree dislocation of the clavicle," said UAE Team Emirates doctor Michele De Grandi.
"It was decided that surgery was not required. Valerio will be off the road for three weeks but should be able to resume indoor training in the coming days."
The 27-year-old will race his eighth year at UAE Team Emirates in 2021, having turned pro with its predecessor, Lampre, in 2014. He has four pro wins to his name, including the GP Bruno Beghelli and a Vuelta a España stage in 2016. He also held the maglia rosa for six days on the 2019 Giro d'Italia.
Last season Conti won the Trofeo Matteotti, beating Burgos-BH rider Diego Rubio to the line in Pescara in August.
