Salman Yusuff Khan and Isha Sharvani have been burning the dance floor of Jhalak Dikhhla Jaa (Colors) and giving some stunning performances. And no hurdle and challenge seems to be affecting them when it comes to their acts. However, an injury scare to Salman really gave them a tough time during rehearsals!! Salman is suffering from a lower back spasm and this makes it tougher for him to exert pressure on his back while dancing. We hear that his doctor had advised him rest for four days which was not practical given the scenario of the reality show. And to top it all, Salman is fasting and this means that he will be performing without any intake of food and water. So how is Salman going to overcome this challenge? Tellychakkar.com managed to talk to the choreographer himself and he said, “Well, it is true that my lower back is in bad shape. It has been a tough week for me, but whenever I am down with injury I only think that ‘This problem is like a black thread on my head, and I just pluck it and throw it away’”. We hear that Salman and Isha will perform an aerial act on the number ‘Tu Hi Re’ this week and they ended up giving a splendid performance and impressed the judges yet again.. Way to go Salman and Isha!!
