Sergei Bubka Jr.fell from a third-floor apartment Thursday morning in Paris and sustained serious injuries, the French press is reporting. The longtime boyfriend of WTA No. 1 Victoria Azarenka and the son of a former Olympic gold medalist (pole vaulting), Bubka was rushed to the intensive care unit of Georges Pompidou hospital. He is said to have sustained multiple fractures, but is no longer in critical condition.
