Jey Uso is set to compete in the Men's WarGames Match tonight at Survivor Series. He will be part of the babyface team alongside Roman Reigns and others inside the double-caged steel structure in San Diego. When everything is said and done and the WarGames dust settles, Main Event Jey could undergo a seismic character change on Monday Night RAW.The YEET Master may turn heel by launching an unhinged attack on LA Knight. Both superstars will compete in the semi-final of "The Last Time is Now" tournament after Survivor Series. There has been quite an interesting development surrounding the two stars lately. A few weeks ago, The Megastar pulled out a fan poster from the crowd with "We Want LA Knight. Not Jey Uso" written over it.Since then, controversies have erupted on a massive scale. The two superstars clearly don't like each other, which has been quite apparent. Adding to that, the WWE Universe has been rallying behind The Defiant One, wanting the 43-year-old to beat Jey in the semi-finals. This collective fan support for LA Knight and criticisms for The YEET Master might prompt the latter to snap.Things may get more intense, especially if Jey Uso loses the Men's WarGames Match at Survivor Series. Following that, he would only have the tournament to prove himself and stay in the spotlight. Frustrations could boil over and the OG Bloodline member may unleash a merciless attack on LA Knight during the semi-finals, officially turning heel in the process.Hence, the above factors tell why Jey turning on Knight is pretty much possible. However, this is currently speculation and only time will tell what actually happens.Jey Uso to face John Cena at Saturday Night's Main Event?Jey Uso battled Rusev this week on SmackDown to advance to the semi-finals of The Last Time is Now tournament. There is no denying that The YEET Master is one of the strong contenders to win the final of this marquee contest and face John Cena at Saturday Night's Main Event next month.However, the biggest question is whether WWE will bank on that. The chances of Jey becoming Cena's final opponent are comparatively low. It is because he is currently involved in several multi-faceted feuds on Monday Night RAW. The company has several options for him on the table at this point.WWE is likely to keep Jey Uso involved with The Vision and Roman Reigns after Survivor Series. There is also a possibility that he could go after CM Punk for the World Heavyweight Championship. Hence, it doesn't look like the company has any plans to put him in John Cena's retirement match.Besides, Gunther is currently the huge favorite to be The Cenation Leader's final opponent at SNME. Hence, Jey might not make it any further even if he reaches the finals of The Last Time is Now tournament.
