#1 No appearance of Undertaker or John Cena

Following the RAW episode this week, it is clear that we could be heading to the Showcase of Immortals without Undertaker and John Cena. Several fans expected either of the two superstars to show up on RAW this week, but it did not happen. The two legendary superstars faced each other at WrestleMania 34, but they have a gigantic possibility to be absent this year. Without a shadow of a doubt, it could be a huge blow for Vince McMahon's billion dollar company if the two superstars do not show up at Metlife Stadium.
Cena returned to the company earlier this year when he had mind-boggling segments with Drew McIntyre. Unfortunately, the 16-time WWE Champion got sidelined due to an injury. With no match at the Show of Shows this year, it will be interesting to see if he makes a special appearance in New Jersey.
Undertaker is undoubtedly one of the main attractions of WrestleMania, and it could be unusual if he misses WrestleMania 35. The Phenom skipped WrestleMania 16 due to an injury, and he might miss the Show of Shows after 19 years.
