On the December 1, edition of WWE RAW, LA Knight defeated Jey Uso to advance to the finals of the Last Time is Now Tournament. The Megastar will face Gunther, who defeated Solo Sikoa to book his spot in the finals.While Knight is the underdog against the former World Heavyweight Champion, he still has a good chance of winning the tournament. If he can defeat Gunther and become John Cena's final opponent, here are four things that could happen afterwards.4. He could defeat John Cena in the legend's final WWE matchLike most legends in pro wrestling, it seems likely that John Cena will also go out on his back. As a result, LA Knight could defeat the Never Seen 17 in his final match at Saturday Night's Main Event on December 13.This would give him a huge boost and allow the company to push him as the next big babyface in the promotion.3. LA Knight could potentially turn heelRight now, LA Knight is one of the most beloved babyfaces in the company. His character is confident, cocky, and has a healthy amount of arrogance. However, it always seems like there's a limit to how much he can express himself as an anti-hero babyface.A heel turn would seemingly allow Knight to unlock the full potential of his character by becoming even more edgy and pulling out all the stops to get to his goals. Moreover, it would also be a good way to build up to his match with Cena if he turns heel right after winning the tournament, since the veteran has reverted to being a heroic character.2. He could win the 2026 Royal RumbleLA Knight defeating the greatest of all-time in his retirement match would be the perfect platform to catapult him into the main-event picture for good. So far, The Megastar has been right outside the world title picture, and could use this opportunity to become a permanent fixture in the main event scene.To give him even more credibility, WWE could book the former United States Champion to win the 2026 Royal Rumble. While Roman Reigns has been teased as the potential winner of the bout next year, the OTC doesn't need to win the Rumble again for a world title shot. On the other hand, Knight could use the credibility boost from winning the Royal Rumble Match to become a serious contender for the world title.1. He could directly earn a world title shotWhile Bron Breakker is the number one contender for CM Punk's World Heavyweight Championship, Cody Rhodes could do with a new rival if his story with Drew McIntyre ends soon.If LA Knight defeats John Cena, he could directly earn a WWE Championship match against Cody Rhodes at the Royal Rumble. This would become an even bigger affair if he were to turn heel in the coming weeks, allowing his character to do everything possible to dethrone Rhodes.While Gunther can boast of retiring Goldberg at Saturday Night's Main Event earlier this year, Knight seemingly needs the win more to establish himself as a top star in the company. All things considered, defeating John Cena in his retirement match would be the best way for Knight to finally reach the level he is destined for.
