4 Impending WWE Superstar Retirements That Will Leave The WWE Universe In Tears

Unfortunately, "goodbyes" are just another aspect of sports entertainment, and they are totally out of our control. Whether WWE Superstars retire or leave due to career-ending injuries, to pursue other career aspirations or the fact that they have wrestled as long as their bodies can handle, the reason definitely doesn't make it any easier on their loyal fans -- just look at wrestlers such as Edge and Paige who were not in control whatsoever over their shortened careers, fans were still terribly upset regardless...

Every year, a couple WWE stars end up leaving the company, with some being released, a couple asking for their own release in search of greener pastures, and of course, some legends retire. The landscape of the WWE is changing at an ever-so-quick pace, and many of our favorite Attitude Era and Ruthless Aggression Era Superstars are slowly fading out into retirement with each passing year -- there are only a few remaining on the current WWE roster.

We are currently at a bit of a "crossroads" period of time in WWE, as the company is transitioning to the "New Era" with up and coming Superstars at the forefront (Roman Reigns has now replaced John Cena as the top merch. seller) -- there are also a number of seasoned wrestling veterans who are very close to retirement as we speak, Cena included. Today, we will take a closer look at 4 impending WWE Superstar retirements that will leave the WWE Universe in tears...

#4 Kane

"The Big Red Machine" has been a staple in the WWE for over 20 years now...

One of the biggest legends in the business, "The Big Red Monster" Kane has done all there is to do in sports entertainment. For well over 20 years now, Kane has sacrificed and dedicated his body, time and energy to the WWE, and he has undoubtedly helped keep fans intrigued in the product for many years -- some fans are a bit harsh towards Kane now a days due to the fact that Kane's slightly stale, but we all respect the former WWE World Champion none the less for his contributions to the business.

Despite being a fixture in WWE to this very day, it is becoming evident that Kane is slowly but surely transitioning into his new career as a politician (Kane is the current Mayor of Knox County, Tennessee). Some fans may moan when they hear that infamous music hit, but before you know it, we will have heard and seen the last of Kane in WWE as an active in-ring competitor.

Although there's a good chance Kane will make sporadic appearances for years to come beyond 2019, it's doubtful Kane will be a wrestler for much longer -- Kane's impending retirement will definitely be a sad day for many...

#3 Sheamus

Sheamus has been suffering from a potentially career-ending injury for some time now...

"The Celtic Warrior" Sheamus may not be the most relevant WWE Superstar on the roster as we speak, but the former 4-time World Champion is undoubtedly a wrestling veteran most fans respect. Just like Kane, Sheamus has accomplished all there is to in WWE, and he is definitely just enjoying the bit of time he still has in his in-ring wrestling career alongside Cesaro.

For those of you unaware, Sheamus has been suffering from a potentially career-ending injury (spinal stenosis) since late last year, and this is the same kind of injury which forced "The Rated R Superstar" Edge to retire prematurely.

It's clear Sheamus is wrestling on borrowed time right now, and it's doubtful the Irishman will be wrestling much further beyond 2019. Apparently, the WWE have been attempting to "protect" Sheamus from taking too many bumps as of late, as Vince knows Sheamus' condition will only worsen with more in-ring abuse. Some fans never regarded Sheamus as being a great main eventer in WWE, but his presence will certainly be missed by many once his final wrestling day comes in the not-so-distant future...

#2 John Cena

It will truly be a sad day when we see the last of John Cena in WWE...

Love him or hate him, the 16-time World Champion John Cena has unquestionably carried the WWE through many tough times for much of the past decade and a half. John certainly dedicated a large chunk of his career to the WWE, and he was about the most loyal employee Vince McMahon could've ever asked for -- a true "WWE guy" for life.

However, as the years continue to press on, John Cena has been slowly fading out of the wrestling spotlight, and he is no longer the face of the company -- that position has now officially been taken over by "The Big Dog", Roman Reigns.

While John Cena has stated that he never intends to fully "retire" from WWE, the in-ring days of John in sports entertainment are limited to say the least. John is exhausted from the strenuous WWE travel, and he is enjoying time out of the ring to pursue other career aspirations -- basically, following in Dwayne "The Rock" Johnson's footsteps as an actor.

John Cena has undoubtedly earned his retirement, and when he decides to call it quits (very likely before 2020), the WWE Universe will be rocked and left in tears...

#1 The Undertaker

The Undertaker is perhaps the greatest WWE Superstar of all time -- an absolute living legend...

The Undertaker is arguably the greatest wrestling Superstar of all time, and his legend continues to grow every year -- 'Taker is still going strong in 2018 at the astonishing age of 53 years.

It's clear Vince McMahon has been relying on established veterans such as Kane, The Undertaker and Shawn Michaels to help draw in fans during these slow periods in WWE, but unfortunately, McMahon will be unable to rely on "The Deadman" to be at his "beck and call" for much longer -- The Undertaker is extremely close to that dreaded retirement.

Without question, The Undertaker's body is beginning to break down from the countless years spent inside the squared circle, and most fans would agree that Undertaker won't be able to wrestle for much longer. Despite seemingly "retiring" after WrestleMania 33, The Undertaker has since resurfaced in WWE many times, and he is currently set to go one-on-one against Triple H at the Super Show-Down in Melbourne, Australia this Saturday.

Although it's likely that The Undertaker will perform at next year's WrestleMania 35, it's highly probable that 'Taker will call it quits after 2019 -- fans will be left in tears when this day occurs...
