Sylvester Stallone has revealed that while filming “Rocky IV,” he was hit hard by Dolph Lundgren and had to be taken to the hospital.

“He pulverized me,” Sylvester Stallone says in a documentary about the film’s production that can be found on the actor’s YouTube account. “I started to feel some discomfort in my chest later that night, though I didn’t notice it at the time.”

Stallone compared the injury to being thrown against the steering wheel of a car following a collision.

“When my blood pressure shot up to 260, they thought I was going to be talking to angels,” he claimed.

According to the actor, he was flown from Canada to St. John’s Hospital in Santa Monica, California, for four days in the intensive care unit.

“I’m in the intensive care unit, and the only other people here are nuns,” he claimed. “I was then forced to return to the arena and complete the battle.”

The hit to the chest delivered by Lundgren while playing the massive Soviet boxer Ivan Drago is included in the film, according to Stallone.

“How could you possibly rule out that scene?” Stallone believes.

“Rocky IV,” starring Sylvester Stallone as the tenacious fighter Rocky Balboa, is the fourth installment in the popular “Rocky” franchise. He has already proven himself worthy of the title of world boxing champion in the fourth film, and after learning that Drago has killed his friend Apollo Creed (Carl Weathers), he flies to the Soviet Union to face him.
