It seems like The Judgment Day might be in trouble after the news of JD McDonagh suffering a legitimate injury surfaced. McDonagh was pushing to regain the World Tag Team Championship with Finn Balor over the past few months before he got hurt. However, it looks like the pursuit has now come to an end due to his surgery.Given the situation surrounding the 35-year-old star's injury, the faction is likely to consider finding a suitable replacement for him. In this listicle, we will look at four replacements for JD in The Judgment Day.#4. Rey FenixRey Fenix signed with WWE earlier this year. He is best known for his time in AEW, where he wrestled for six years. However, many believe that the 43-year-old luchador has had an underwhelming run so far in the Stamford-based promotion. This is arguably because of his lackluster booking and poor win-loss record.While the former AEW champion might face some difficulties regaining momentum as a babyface, the company might consider booking him to turn heel. Fenix could embrace his dark side and join The Judgment Day as JD McDonah's replacement.#3. & #2. Aleister Black & Zelina VegaAleister Black and Zelina Vega's on-screen relationship has been in full swing after the real-life couple came together as a tag team on WWE SmackDown. They have been at odds with Damian Priest over the past few weeks on the blue brand.However, it looks like the creative might consider ending the rivalry between the real-life couple and Damian Priest after The Terror Twins (Priest and Rhea Ripley) defeated Black and Vega last week.The creative team might move Alesiter Black and his wife to WWE RAW and align the duo with The Judgment Day. Given the momentum the heel couple has gained since coming together, Dominik Mysterio and his crew could benefit from working with them.#1. AJ Styles might join The Judgment DayAJ Styles has a rich history with The Judgment Day on WWE RAW. Despite the existing bad blood between the heels and Styles, The Phenomenal One could eventually turn heel and join forces with the heel faction.Despite holding the World Tag Team Title, many still believe AJ Styles has yet to regain his standing as a formidable competitor, and embracing a more sinister side might be what he needs to achieve the goal. Hence, Styles potentially joining the heel faction and taking over its leadership role might be a great decision.Moreover, since The Judgment Day aims to regain all the gold on the red brand, having AJ Styles as JD McDonagh's replacement would bring the World Tag Team Championship back to the group, as Dragon Lee is likely to join the stable as well.
