‘The World’s Strongest Man’ Mark Henry announced his retirement back in 2017 and he made some sporadic appearances after that. But there was no official news of him coming back to action again until his recent interview with The Wrestling Inc. Daily where he declared that there is a chance of him returning to action again.
But Mark Henry also clarified that he may wrestle outside of WWE. He was also asked about the possibility of wrestling on the All Elite Wrestling. Here are some glimpses of the interview;

When asked if he wants to wrestle again Henry expressed his wish to wrestle within the next six months;
“I haven’t thought one bit about who, or where or when. Well, the when is going to be after my birthday,” Henry revealed. “It’s going to be after June 12. I’ll be 50 years old, and I want to be able to say I wrestled after I was 50 and had a good match. I wrestled in four decades, and that I was able to help somebody in the process or bring attention to somebody that nobody knew. So that’s that’s the whole point in me doing it.”

Henry was also asked if he wrestles again, where would he wish to wrestle again, if he wants to wrestle in the AEW, SWE or in WWE maybe;
“I don’t know. I’m kind of right now a WWE lifer but only God knows what the future holds,” Henry stated. “I plan on doing the best that I could do wherever I’m wanted, and if the WWE wants me, then I’m going to do my best there.”
As it is known to all, Mark Henry is a two times WWE World Champion and around ten years he was finally being given all the recognitions he actually deserved.

It is also known that Mark Henry was one of the few individuals in WWE whom they considered as a potential wrestler to beat the famous streak of the Undertaker. But Henry said that he was never been ready to take such a responsibility.
We wish wherever the 49 year old goes, he gets the right treatment that he deserves.
