It was confirmed earlier this week that the current plan is for Jinder Mahal to face Brock Lesnar at the upcoming Survivor Series event with John Cena as the special guest referee for the match.
Dave Meltzer mentioned on today’s installment of Wrestling Observer Radio that the reason WWE is having Cena as the special guest referee in the Lesnar vs. Mahal match is to set up a future match between Mahal and Cena for the WWE Championship Title.
Meltzer speculates that Cena will screw Mahal out of the match, allowing the victory to Lesnar. Cena and Mahal would then meet for a match at a later date, presumably WrestleMania.
