Sylvester Stallone's hairline fracture in the neck wasn't the only injury he's sustained on a film set. In fact, another "The Expendables" co-star, Dolph Lundgren, sent him to the emergency room during the creation of 1985's "Rocky IV," which sees Rocky Balboa (Stallone) take on Ivan Drago (Lundgren) in the ring.
"I gave him orders to try to knock me out while the cameras were rolling," Stallone told The Mirror. "At one point, he hit me so hard on the top of the head, I felt my spine compress. He then hit me with an almighty uppercut." Once home, Stallone could feel his chest swelling and was flown to the hospital. Turns out, Lundgren's punch to the ribs compressed his heart. "If it had swollen any more, I would have died," said Stallone. "After that, I was like, 'Dolph, it's only a movie, bro ... '"
Another injury occurred while training for 1979's "Rocky II." In a bench pressing competition with Mr. Universe, Franco Columbu, Stallone tore off his pectoral muscle, an incident that resulted in 60 stitches and tattoos to cover up the area. Additional injuries over the years include a pulled calf muscle, dislocated shoulders, and a painful fall on the back, which required the installation of metal. Stallone told Hello! Magazine, " ... so if I'm squeaky, then deal with it. It's not my shoe, it's my back."
