In the latest episode of SmackDown, WWE star Jacob Fatu was mysteriously taken out backstage. This happened moments before his match against Drew McIntyre in the main event of the night.After seeing this, General Manager Nick Aldis and the officials immediately sent Fatu to the medical facility, and now the star is seemingly written off from television. Reports before SmackDown already disclosed that Fatu was dealing with a non-wrestling injury, and the angle on the recent show appears to have been done to write him off.A source also revealed that Fatu was recovering from a dental procedure and has not been cleared for in-ring action yet. Meanwhile, in this article, we will be looking at four WWE stars who might be revealed as the mystery attacker of Jacob Fatu on SmackDown.#4. Drew McIntyreWhen Nick Aldis blamed Drew McIntyre, the latter revealed that he had no connection with the mysterious attack. However, it's crucial to note that McIntyre is a heel, and there is no certainty that he was telling the truth on SmackDown.Considering this, it's probable that Drew could be the one who first attacked Jacob Fatu backstage. Later, he tried to be innocent in front of the SmackDown General Manager to avoid any repercussions for his actions.#3. Solo Sikoa & MFTSolo Sikoa and his MFTs already have a heated history with Jacob Fatu.In fact, it was The Samoan Werewolf that disrupted Solo Sikoa's title defense against Sami Zayn on the August 29 edition of SmackDown, leading to the title switch. So, it won't be a surprise if Solo and his Family Tree are disclosed as the ones who took out Fatu on the blue brand.This could have been done to re-establish their dominance on the Friday Night show.#2. Randy Orton might be the mystery attacker on WWE SmackDownجح| Jihder @Honorary_jihderLINKGuys my mind tells me that Randy Orton was behind the assault on Jacob Fatu but I can't prove it #SmackDownThe reason why Randy Orton is in the list of potential attackers is that The Viper might have done this to protect his friend Cody Rhodes. Over the past few months, WWE has dropped significant hints about the heel turn of Orton.Additionally, The Legend Killer was notably missing from the blue brand, which sparks the chances that he could be the mastermind behind the attack. With this, Orton could have sidelined Fatu from the Undisputed WWE Championship race and protected Rhodes' title reign for now.#1. Undisputed WWE Champion Cody RhodesBUTCHER @BILLYxBUTCHERLINKHe is neither a babyface nor a heel,he is the American Nightmare Cody freaking Rhodes.If Jacob Fatu competed against McIntyre on SmackDown and somehow emerged victorious, then he would be the challenger for Cody Rhodes' Undisputed Championship. In the main event of the blue brand, The American Nightmare also appeared uncharacteristically more vicious and aggressive towards the Scotsman.He even got himself disqualified in the match by using the title as a weapon. With Cody seemingly on the horizon of his heel turn, it won't be a surprise if he is disclosed as the mystery attacker of Jacob Fatu.The Undisputed WWE Champion might have done this to put The Samoan Werewolf on the shelf and to keep him away from the title.
