Superstar Shah Rukh Khan underwent a shoulder surgery at the Lilawati Hospital today after he injured himself while shooting for his upcoming movie Chennai Express and is doing fine. 47-year-old Shah Rukh suffered the injury after performing some daring stunts for director Rohit Shetty’s action drama. “He is doing fine and will be discharged in one-two days. He has been advised not to any heavy action,” a source close the actor said. Shah Rukh’s son Aryan, who is studying in London, had also flown down to be by his father’s side. The surgery was supposed to have been done earlier this month in London but was postponed due to the actor’s busy schedules. Despite his injury, the actor had refused to use body doubles for Chennai Express and performed his own stunts. He also performed at the TOIFA awards in Vancouver recently. This is actor’s eighth surgery, last one being in 2010 when he injured himself while shooting for his home production, RA.One. After recuperating, Shah Rukh will start promoting Chennai Express and begin work on Farah Khan’s film Happy New Year.
