5 WWE Superstars who have come back from rehab to find success

#2 William Regal

William Regal battles with Cesaro

William Regal has basically wrestled pretty much everywhere there is to wrestle during his very long and storied career. The British Superstar is a lot more than the posh English guy he portrayed for the most part in WWE.

For long periods in his career, however, Regal suffered from quite severe substance abuse. Not the kind of man you would imagine having those issues, but Regal has said there are large parts of his life and career that he can't even remember.

Regal was actually checked into rehab during his first stint with WWE in 1999. He would later leave the company for WCW before returning at the end of the year 2000. He has been with the company in a variety of roles ever since.
