WWE fans online are still speculating about the identity of the mystery attacker who returned on the go-home edition of RAW ahead of Saturday Night's Main Event XLII. Amid the widespread theories, there is now a possibility that a Judgment Day member might be revealed as the hooded assailant who assaulted Rey Mysterio.During the show, Logan Paul ambushed Mysterio as he was making his way to the ring for a match. However, the WWE Hall of Famer managed to get the upper hand over The Maverick, but was then attacked by the mystery man from this year's Men's WarGames Match. As the referee tried to help him up, Paul knocked him out with the brass knuckles before LA Knight ran down to make the save.Given this incident, there is now speculation that Rey Mysterio's mystery attacker might be JD McDonagh. The former World Tag Team Champion was nowhere to be seen during The Judgment Day's segment at the Clubhouse this week, and a fan was quick to notice that. This has led many to suggest that he could be the hooded assailant.Rey has had a long-standing feud with Dominik Mysterio and The Judgment Day in WWE. Considering the recent face-offs between the father and son, the creative team might consider developing a storyline involving the duo. Hence, revealing McDonagh as the mystery attacker could further escalate Mysterio's heat with Dominik and his crew.That said, while this angle is far-fetched, it is not impossible. Only time will tell if this will eventually come to fruition.Liv Morgan to kick Raquel Rodriguez out of The Judgment Day after WWE RAW?After making her return at this year's Survivor Series: WarGames, Liv Morgan expressed her intentions of capturing the Women's World Championship by confronting Stephanie Vaquer backstage on last week's episode of WWE RAW.
