Hulk Hogan said in a recent Facebook post that he injured Sylvester Stallone while filming a fight scene in the movie "Rocky."

Growing up as a kid, "Rocky" was one of my all-time favorite movies. However, I just learned something interesting about the filming of the original movie, Hulk Hogan actually broke Stallone's collarbone while filming a scene in the ring.

Hogan posted that his knee caught "Rocky" with a "stiff shot" and Stallone actually broke his collarbone while filming the movie. More exciting than that, Hogan reports that Stallone continued filming the movie for eight days with the broken bone! Yeah!!

This is pretty amazing. To know that Stallone refused to address the injury until the filming was complete. Perhaps his determination to complete this movie is what makes it so great.

As a kid, the scene when Rocky and Hogan fought frightened me. Still, its always pretty cool to read what happened "behind the curtain" during filming.

Now, if you would excuse me, I'm going relive a part of my childhood years again.
