Actor R. Madhavan says he can39t be a part of Rohit Shetty39s "Simmba" due to an injury.Madhavan underwent a shoulder surgery last month, and since he is recuperating, he had to even withdraw from joining actor Saif Ali Khan in Navdeep Singh39s historical drama, which is heavy on action scenes. Now the actor also won39t be seen in "Simmba", in which he was reportedly going to play the villain."Hey folks... So I am a huge crazy fan of Rohit Shetty and his films. As is my son. It breaks both our hearts that I39m not able to be a part of this film because of my injury. I39m well on my way to recovery but this is a huge opportunity and excitement lost," Madhavan tweeted on Sunday.Madhavan was last seen in web series "Breathe", which explores the life of an ordinary man facing extraordinary circumstances.""The injury kind of ruined everything," the actor had told IANS in an earlier interview after he had to opt out of the Saif-starrer.
