Jey Uso and CM Punk are set to battle for the vacant World Heavyweight Championship at Saturday Night's Main Event on November 1. The two had an intense promo segment on the go-home edition of WWE RAW tonight in Anaheim, California.We are guaranteed to see a new world champion this Saturday, but it is anybody's guess as to who takes home the gold. With that in mind, here are four potential finishes for CM Punk vs. Jey Uso at Saturday Night's Main Event.4. Jey Uso could win the title by turning heelOn WWE RAW tonight, Jey Uso told the crowd that despite Roman Reigns and Jimmy Uso giving him advice, he would listen to himself and win the title on his own. WWE could double down on Jey's newfound aggression and have him win the title clean over CM Punk.Such a scenario would legitimize Uso's character change and would also make fans take him more seriously. The creative team could also pull the trigger on Uso's heel turn, giving him a chance to explore a new character as a heel champion.3. Jimmy Uso could cost Jey Uso the titleJimmy Uso confronted Jey Uso backstage after the latter's promo segment with Punk. Although the brothers had a brief argument, they seemingly made up later on in the show.However, Jimmy might not forgive his brother for 'betraying' him in the number one contender's battle royale so easily. Still angry over being eliminated early, Big Jim could cost his brother a world title again. But this time, it would be out of revenge.2. The Vision could interfere and cost CM Punk the titleSeth Rollins cashed in his Money in the Bank contract on CM Punk at SummerSlam to regain the World Heavyweight Championship. The Vision has been at odds with Punk ever since it was formed, and their feud could continue despite Rollins being booted from the group.At Saturday Night's Main Event, Bron Breakker and Bronson Reed could cost Punk the chance to become the world champion. They could take out both competitors and the referee, with Punk getting the worst of the exchange.Jey Uso could take advantage of the situation and somehow win the title, pushing his character closer to a heel turn.1. CM Punk could win the title cleanPunk held the World Heavyweight Championship for a mere five minutes and nine seconds at SummerSlam before Seth Rollins cashed in on him. At Saturday Night's Main Event, he could overcome Jey Uso clean to regain the title.Rollins always claimed that Punk would never be a world champion as long as he was around. And now that The Visionary is sidelined from WWE with a legitimate injury, the company could put the title on the Straight Edge Superstar.CM Punk has shown time and time again that he still has what it takes to hang with the best. The Second City Saint defeated Gunther cleanly at SummerSlam and could do the same against Uso to claim the title for a second time.
