With two days to go for the International Indian Film Academy (IIFA) Awards, the line-up of stars performing at the awards ceremony is getting bleaker. After Vaani Kapoor backed out of her gig, Shahid Kapoor — who was scheduled to put up a power-packed performance at the awards night on June 24 — has bowed out of the Bangkok event. Kapoor had no option but to pull out at the last minute owing to a back injury he sustained during the shooting of Batti Gul Meter Chalu.

A source close to the actor reveals, "Despite suffering a major back injury while shooting in Tehri last week, Shahid continued filming as he was required to wrap up the movie by mid-June. After returning to Mumbai earlier this week, he promptly dived into the dance rehearsals for his IIFA gig. It was while attempting a tricky step that he suffered a back spasm and was advised against any strenuous activity by the doctor. Although Shahid was scheduled to fly out to Thailand last night, he called off the plan. The IIFA organisers were fairly understanding about it."
