Pro wrestling, despite being pigeonholed as a fake sport with an emphasis on entertainment over physicality, is a very dangerous field of employment.
The WWE's recent depth issues, as a result of retirements and injuries, inspired this article as the moving and shuffling of stars is just another routine part of professional wrestling.
It's safe to say that there are few, if any pro wrestlers who can say that they've gone their whole career without suffering a single injury.
Injury is basically the name of the game.
However, there have been many WWE superstars who have struggled with injuries more than others.
Wrestlers who just can't seem to stay healthy for too long before returning to the vaunted hospital room where superstar surgeon James Andrews (pictured above) is usually called upon to work his magic.
While nobody wants to be considered injury-prone, this unenviable tag in the context of pro wrestling is often a testament to the WWE's faith in a performer's talent, potential, or drawing power.
WWE is a machine that does not stop for anybody. Many times, those who get injured simply lose their spot.
However, it is hardly a mere coincidence that the superstars mentioned on this list are all top guys and/or former world champions.

This isn't for the faint of heart.
These are the five most injury-prone wrestlers in recent WWE history.
