DISCLAIMER: I am not criticizing Rey Mysterio, This is only an article regarding his future.
Rey Mysterio is indeed the best luchadore wrestler WWE has had between 2002 and now. He is packed with all the skills that WWE want. But when ever he enters the ring, I get worried as he has endured several injuries such has knee injury, concussions etc. As he is getting older (38 years old now), His injuries are getting worse. He returned and gone a couple of times because of the injuries. recently Mysterio returned on January 27, 2013, at the Royal Rumble, entering the Royal Rumble at number fourteen but was eliminated by Wade Barrett.
He was then later injured by the returning Mark Henry and he is scheduled to return before August. The thing is that Rey Mysterio is reaching the end of his career and has left many questions. With his retirement, WWE will look for new fresh masked stars.
These wrestlers will also get an opportunity. Currently WWE has signed Samuray Del Sol and Mascarita Dorada which is efficient for WWE. In my personal opinion this should be Rey Mysterio’s one last run with a good storyline.

I agree. It’s a shame to say that Rey Mysterio is definitely in the twilight end of his career.
It’d be nice to see him pass the torch onto a new luchadore in a retirement match. Del Sol is a personal favourite of mine and I would mark the fuck out if that happened.

I read Rey Mysterio’s book recently and it made me sad that Rey has been injured so much during his WWE career. He’s fun to watch when he’s healthy. I’ve been to 9 WWE shows and I think I’ve seen Rey only twice! I would love to see Rock vs. Rey because that’s a match both of them have wanted to do, but it hasn’t happened yet.

I think he should retire. His knees have been destroyed over the years.

I agree with you. As fans we care about wrestler’s well being, he should retire. I’d hate to see him crippled by the time he’s 50.

You people are absolutely correct, He is currently having a physioTherapy and has ligaments in his knee. The latest news is circulating that he may come two or three weeks before Summer Slam.

Rey is getting older but because he gets such a great reception and is loved by all fans it must be hard to end that career, similar to the Undertaker. But yeah, I don’t want to see him hurt any worse or seriously injured. I would love for WWE to push Kofi or Evan Bourne.
