CM Punk and his allies are set to face Paul Heyman's team on Saturday at Survivor Series: WarGames. Both squads have been blowing the roof off with their intense rivalry, and fans can't wait to see which team finally secures the victory at the upcoming premium live event. However, Seth Rollins might return in a shocking twist in San Diego and replace an eight-time champion in Punk's team.The Visionary reportedly underwent surgery due to a shoulder injury he sustained during his match against Cody Rhodes at Crown Jewel: Perth. On the following RAW, Rollins was backstabbed by The Vision, and has been on hiatus since then. That said, it's possible that the creative team might be planning a huge surprise for fans in San Diego.In a massive turn of events, Seth Rollins might mysteriously take out Jimmy Uso backstage before the Men's WarGames Match, something the company has done several times in the past. This attack could cause Big Jim to sustain an injury, preventing him from competing. As a result, Rollins would then step in as his replacement for the 10-man showdown.Since Jimmy Uso appears to be the most underrated superstar among the babyfaces, fans will likely not be bothered by the storyline twist of having The Visionary replace the 8-time tag team champion in the star-studded squad.If this happens, it could serve as an element of surprise in the Men's WarGames Match. Moreover, it could enable The Visionary to target Bron Breakker and Bronson Reed for turning on him, while his enmity with CM Punk will also add an extra layer of intrigue to such a scenario.As of now, this angle is very speculative, and nothing in this regard has been confirmed. Fans will have to wait and see the turn of events at Survivor Series.CM Punk to defend the World Heavyweight Championship against Seth Rollins after WarGames?If the above scenario comes to fruition, Seth Rollins may maintain his feud with CM Punk despite potentially being on his team for the Men's WarGames Match.The Visionary was initially scheduled to face Punk for the World Heavyweight Championship before Adam Pearce stripped him of the title due to his injury. Hence, Rollins might aim at regaining the gold after his potential early return, since he was never defeated for it.As for Roman Reigns, the company could factor him into a storyline with Cody Rhodes for the Undisputed WWE Championship, since he has revealed his intention of becoming a champion again after potentially taking down The Vision at WarGames.If this happens, the Stamford-based promotion might consider extending the storyline to WrestleMania to generate much greater fan interest for The Show of Shows next year. That said, this angle is also speculative at this point; only time will reveal what will happen next.
