One of the big mysteries for pro wrestling fans recently is who may have attacked Enzo Amore twice now on WWE's "Monday Night Raw" program. Enzo is one-half of the tag team duo Enzo and Big Cass, who have been involved in several tag team championship battles and other singles feuds.

However, this recent story is raising some eyebrows about who may have orchestrated the beatdown on Enzo backstage that resulted in him being taken away to a medical facility for treatment. Here are the latest possible WWE spoilers with regards to who attacked Enzo on "Raw."

Tag team attackers?

The visual clues given on WWE "Raw" over the past few weeks are what the WWE has been trying to get the fans to focus on.

During an interview that Charly Caruso was conducting backstage, a tag team was spotted in the far distance behind her, showing that they were backstage despite reports they weren't there.

That tag team was Scott Dawson and Dash Wilder aka "The Revival." The duo made their big debut on "Raw" weeks ago when they attacked The New Day. However, Wilder suffered an injury in mid-April at an NXT match so they haven't done much on "Raw" lately. Wilder's injury required surgery and his jaw to be wired shut. Reports indicated he would be out of action for eight weeks, which could have him returning this month.

With that said, it would give Enzo and Big Cass a feud with Dash and Wilder in a few weeks.

It's possible that WWE wanted to keep the story intact while Wilder recovered. However, that's just one theory.

A shocking attacker?

The biggest surprise could be if the other WWE spoilers and WWE rumors floating around the internet end up coming true. Many fans and some wrestling websites are speculating that it was in fact, Big Cass who attacked his own partner Enzo Amore backstage.

Big Cass has seemed to look surprised by the attacks and "seems" concerned over Enzo's well-being. However, one of the biggest clues may have been when "Raw" commentator Corey Graves joked he'd like to shake the hand of whoever beat down Enzo. On a "Raw" segment in the past week, Cass went out to confront Graves about suggesting he was involved in the attack.

Graves apologized when he was under fire, and Cass extended his hand to shake Graves' hand.

As far as motivation goes, it wouldn't be the first time a tag team partner has decided he would do better on his own as a solo superstar. Examples over the history of WWE have included Shawn Michaels attacking Marty Jannetty, Seth Rollins attacking his Shield brothers, and more recently Tomasi Ciampa attacking Johnny Gargano at the "NXT TakeOver: Chicago" pay-per-view.

The WWE creative team may have a good story on their hands with this particular plot, as they could spin it to look like the team of Enzo and Big Cass is legitimately feuding with The Revival for a bit of time. When fans are least expecting it, Big Cass could make the big heel turn and admit it was him behind the attack all along.

WWE fans, who do you think was behind the attack on Enzo Amore: Big Cass, The Revival, or someone else?
