Action kings SYLVESTER STALLONE and ARNOLD SCHWARZENEGGER laid up – together.

Arnold Schwarzenegger, 64, and Sylvester Stallone, 65, wound up in neighboring beds at an undisclosed medical facility Wednesday.

The Terminator star posted the pic on his Who Say page, "After all the action, stunts & physical abuse shooting The Expendables 2 and The Last Stand, it was time for a little tune up on my shoulder,"

"Look who was coincidentally waiting in line behind me for his shoulder surgery."

 "Now we're ready for another round of great times and action . . .”

What, no BRUCE WILLIS?
