The wrestling world is emotionally preparing itself to bid John Cena the final goodbye as he walks down that ramp one last time this Saturday. While the air is filled with melancholy, it will be a historic moment. Several superstars like CM Punk and Seth Rollins, with whom Cena had so much history, will reportedly be at Saturday Night's Main Event to be part of this big moment.However, fans may not get to see Randy Orton at the show tomorrow night in Washington, D.C. It is because The Viper is currently in Saudi Arabia for a promotional appearance at Mr. Beast Land. This is part of the ongoing Riyadh Season, Saudi Arabia's annual entertainment festival that runs from October to March and features global stars, concerts, and attractions.Orton may miss John Cena's final show because his promotional activities would conflict with the timing of SNME. Mr. Beast Land runs through the evening of December 12 in Riyadh, while Saturday Night's Main Event starts at 8:00 PM ET on December 13 in D.C., having only an 8-hour time difference. It would be quite a hassle to fly from Saudi Arabia to the USA.However, there are slim chances that he could show up on John Cena's historic night. A direct flight from Riyadh to Washington D.C. takes about 13-14 hours, so if Randy Orton wraps up his Saudi duties by late afternoon or early evening local time, he could board a private jet overnight and land in the city by midday December 13, leaving little time for rest and preparations.Why Randy Orton missed WWE's all-star tribute to John Cena!The wrestling world is emotionally reluctant to bid John Cena farewell. Amid this, the company recently released a heartfelt video where every WWE superstar including Asuka, CM Punk and many more paid a beautiful tribute to Cena. While some did his "You Can't See Me" gesture, others did his trademark salute.However, Randy Orton wasn't there in the tribute video as well, leaving many wondering what the actual reason was. The most plausible explanation for this is that The Viper has been absent from the WWE shows lately.These backstage clips of superstars paying tribute to The Cenation Leader were shot from their recent appearances in WWE shows or PLEs and Orton hasn’t been around lately. Hence, his unavailability could be a major reason why The Apex Predator is not in the recent tribute video.There is no denying that Randy Orton's friendship with John Cena goes beyond the wrestling realm. It will be interesting to see whether The Viper manages to appear at Saturday Night's Main Event to see his good old friend grace the wrestling ring one last time.
