Mumbai, Sept 15: Shah Rukh Khan may step in to do Salman Khan's role in Karan Johar's untitled film, because of the latter's poor health.
Salman Khan has two back to back shooting, Yash Raj's ‘Ek Tha Tiger' and Sohail Khan's ‘Sher Khan' and again the actor needs to fly to the US for his second surgery.
A media report said Dharma Productions may ring up Salman and if he fails to give them dates then SRK may be roped in.
Karan Johar's untitled film will be directed by Rensil D'Silva. It has Katrina Kaif in the lead.
