Mumbai:Actor Sushant Singh Rajput has ended up with an injury while shooting for the last schedule of his upcoming film "Raabta". The 30-year-old actor was performing a daring stunt when a ligament in his right knee tore five days ago. He says the slippery ground where he had to perform the stunts caused him the injury. "We practiced a lot and I could do the stunt properly everytime, but unfortunately on the day of the shoot it was pouring and the ground was slippery. That caused the injury. I am glad that we could still finish the scene as planned," Sushant said in a statement. The extent of Sushant's injury has resulted in the doctors advising him to refrain from running or indulging in any kind of strenuous workout for a month. Directed by Dinesh Vijan, "Raabta" also stars Kriti Sanon.
