5 Moments that changed WWE forever 

#2. Chris Benoit's murder-suicide

Chris Benoit's name was banned from being mentioned in wrestling circles for more than a decade after his death. The events of that fateful night in June 2007 have haunted wrestling fans for the past 13 years, but it's worth noting that there was a small positive to come out of the horrific situation that unfolded.

According to medical examinations, experts diagnosed Benoit with 'severe brain damage', stating that his brain resembled the nature of an '85-year old Alzheimer's patient'. Benoit's heart was also three times the size it should have been and his body contained ten times the normal amount of steroid testosterone despite passing a Wellness Policy test three months earlier.

WWE was forced to change many of its policies following Benoit's death and many of these are for the better. The health of their athletes is now paramount and WWE's concussion protocol has now been changed completely.

Benoit's brain allowed the study of CTE and now WWE forces every star who suffers a concussion to go through Impact testing before they can make their return.

"If a WWE Talent shows symptoms of a concussion or has suffered a concussion, then that WWE Talent will not be cleared for a return to wrestling until he/she passes an ImPACT test and is cleared clinically by a certified physician."
