"A CT scan confirmed a fracture to the right clavicle. Chris will be examined tomorrow (Monday) by an orthopedic surgeon to find out if an operation will be necessary to stabilise his fracture," said Israel-Premier Tech in a statement.
Froome was injured after getting caught up in a mass pile-up inside the first 10km of Sunday's final stage.
At 39, Froome is likely competing in the final season of a glittering career which has yielded four Tour de France triumphs, two Vuelta a Espana wins and one Giro d'Italia victory.
He is also a two-time Olympic Games bronze medallist in the 2012 and 2016 time trials.
