John Cena will compete in his final professional wrestling match on December 13. Meanwhile, the TNA Knockouts World Champion and NXT star Kelani Jordan has vouched for her real-life partner, Carmelo Hayes, to be Cena's final opponent.The Last Real Champion is currently on his Farewell Tour. His next match will take place at the Crown Jewel Premium Live Event against AJ Styles in Perth, Australia. The bout was made official after John Cena took to social media to ask the WWE Universe about their views on running it back with The Phenomenal One.Meanwhile, speaking on Busted Open, Kelani Jordan admitted she was biased and picked Hayes to beat Cena in his final bout. She hoped The Franchise Player could put over the former NXT Champion, which would give Melo's career just the boost it needed."So, I'm biased, so of course I'm going to pick Carmelo Hayes. I think he [John Cena] should lose his last match. If he were able to wrestle, say like Melo, he can be able to put him over, and, like, jumpstart his career more than it already is because being able to beat someone like John Cena, your credibility and equitability goes all the way up," said Jordan. [H/T: Wrestling Inc.]Bill Apter wants John Cena's last match to be against GuntherBill Apter wants Cena's final opponent to be Gunther. The Ring General is currently absent from WWE television.Speaking on The Wrestling Time Machine, Apter suggested that Cena should put over Gunther in his final match. He said:"We don't know who his opponent is going to be yet. A lot of people are speculating it's going to be Brock Lesnar. Cena is going to get the win over Lesnar to get even. But I don't think that's going to happen. What I would like to see happen, there's another guy I want to see come back and be Cena's final opponent. That would be Gunther. I think that would be a great final match. I want to see Cena vs. Gunther in Cena's retirement match. And if Cena doesn't win, it's okay. Gunther gets stronger with the win over John Cena."Cena's next appearance is scheduled for Crown Jewel: Perth. He will also appear on RAW twice and Survivor Series: WarGames before his final match at Saturday Night's Main Event on December 13.Only time will tell whether Hayes or Gunther will be Cena's final opponent.
