Defending champion Janko Tipsarevic from Serbia has withdrawn from the ATP Chennai Open due to a rupture on the heel tendon he sustained in Valencia in October this year.
The World No 36 said in a statement that he is still to recover fully from the two-month-old injury.
The 29-year-old has been a regular at the event and is one of the tournament’s favourites.
