Last year, Vivek Oberoi had broken his leg while shooting for Mani Ratnam's film in Kolkata. And now, while shooting for Subhash Ghai's new venture 'Kisna', he lost balance and feel from horseback. It happens at Ranikhet in Almora district of Uttaranchal. His father Suresh Oberoi and friend Aishwarya Rai telephoned him to know about his condition.
