5 WWE Superstars whose careers could end a lot sooner than we think 

#4. Sheamus

Teenage Mutant Ninja Turtles: Out Of The Shadows Dublin Premiere

We aren't sure what Sheamus' shelf-life in WWE is, but he may become a superstar who ends up going the part-time route. We don't blame him as he's certainly earned that privilege after a decade with the company, having won virtually every accolade there is to minus the Intercontinental Championship.

We may still see Sheamus appear for a couple of years, but that isn't as long as we think, given how fast time flies by. The Wrestling Observer Newsletter reported that Sheamus has been dealing with a spinal stenosis issue for a while now. This is similar to what Edge and 'Stone Cold' Steve Austin had.

When I tried to ask Sheamus about the condition myself, Cesaro was quick to shut me down and they were evasive about the question. Make what you will of that, but the reality is that wrestling can have some grueling effects. That is the reason why Sheamus has been in a tag team for the last 3 years and now that they have separated, we haven't seen much of him.

Hopefully, he has the best run that he can while he has time.
