New Delhi: Playing squash without proper guidance has taken a toll on Sonu Nigam's health and now, he will have to go under the knife because of it. In an interview with SpotboyE, the 42-year-old singer said that due to his damaged knee cartilages, he will undergo a surgery on the left knee only after his right leg gets better. It is being that in the wake of his knee injury, the singer has called off all his concerts until September.
