"Transformers 2: Revenge of the Fallen" star Shia LaBeouf may have seriously injured his hand in an offset car crash, causing major production problems.

But he's got nothing on Ramon Rodriguez who plays Leo — who revealed at today's press conference at the Four Seasons that he separated a shoulder while SHOOTING A SCENE.

And that one intensely painful take ended up being in the movie. Not only that, but  judging by his director Michael Bay's stunned reaction this afternoon, Bay didn't even know about Ramon's injury until today.

Watch the video to hear Ramon — who also stars in "The Taking of Pelham 1 2 3" — explain how it happened.

It sounds insane!
