The rumors surrounding WrestleMania this year will only intensify as the event gets closure, but WWE commentator Corey Graves is certainly not doing anything to help matters.

The former wrestler turned-valued ringside voice on Monday nights took the opportunity to send the rumor mill into overdrive during the latest episode of the WWE After the Bell Podcast.

He said that those in the know, know of a big return WWE is lining up for the Showcase of the Immortals, and while he stopped short of revealing who that surprise might be (obviously) he certainly didn't hold back in hyping it up.

“And who knows, if the rumors do in fact prove to be true, we may have another familiar face back in the fold between now and The Showcase of the Immortals,” Corey Graves said.

“This is one of those ones where: if you know, you know. I’m not going to speak to it any longer. I’m going to feed the rumor mill, that’s what I’m doing, I’m feeding the rumor mill. I’m stoking the flames and I am pouring gas on the fire. If the rumors are true, I couldn’t be more thrilled.”

It's very possible that Graves is just trolling here, but we do know that WWE is hoping to pull out all of the stops for this year's WrestleMania, so anything is possible at this point.

Who Has Been Rumored To Appear At WrestleMania

Stone Cold Steve Austin hasn't wrestled in a WWE ring for many years, but there have been reports suggesting that WWE is hoping to get him back for a marquee match against Kevin Owens on the Grandest Stage Of Them All.

Former AEW founder and EVP Cody Rhodes also recently became a free agent and he's even been alluded to a few times on WWE programming. Could the wrestler who symbolically smashed a throne resembling Triple H return to the company he left?

We've also seen the likes of Jonny Knoxville and Logan Paul set foot inside the ring recently, with both expected to be wrestling at WrestleMania, with Knoxville lined up to challenge Sami Zayn for the Intercontinental Title and Paul teaming up with The Miz to take on Rey and Dominik Mysterio.
