WWE Saturday Night's Main Event XLII was a great show and also marked the end of an era. During the event, John Cena ended his iconic career in pro wrestling, losing to Gunther in his final match as an active wrestler. Meanwhile, Cody Rhodes went toe-to-toe against NXT Champion Oba Femi in a highly anticipated bout.Both champions delivered an intense battle before Drew McIntyre interfered, causing the bout to end in a no-contest. However, the babyfaces were not pleased with The Scottish Warrior ruining their match and took him out. They eventually endorsed each other after delivering a competitive bout.Now, let's look at four ways WWE could reward Oba Femi after Drew McIntyre cost him at SNME XLII.#4. Oba Femi could be called up to the main roster while he still holds the NXT ChampionshipOba Femi has achieved notable success in WWE's developmental brand since joining the company, securing victories in most of his matches. Given his potential, fans speculated about his promotion to the main roster after previously dropping the NXT Championship to Ricky Saints at No Mercy. But the authorities didn't pull the trigger.Femi was able to regain the title from Saints at Deadline to earn a shot against Cody Rhodes at Saturday Night's Main Event XLII, only for Drew McIntyre to ruin his moment. Hence, there might not be a more perfect reward for the star than to be promoted to the main roster while still holding the NXT Championship.#3. He could be booked in a match against Drew McIntyreAfter Oba Femi is potentially promoted to the main roster, the creative team might consider booking him in a match against Drew McIntyre. This could enable him to get revenge against The Scottish Warrior for ruining his moment against Cody Rhodes at SNME XLII.If this happens, Drew McIntyre and Oba Femi could excite fans with their feud on SmackDown. McIntyre has seemingly established himself as a top heel on the blue brand show. As for Femi, he has made a name for himself in NXT. Hence, a match between the duo could be a must-watch.#2. Femi could get a rematch against Cody RhodesFollowing the turn of events at Saturday Night's Main Event XLII, it's obvious that Oba Femi still has unfinished business with Cody Rhodes. Therefore, it makes sense for the creative team to consider booking a rematch between the duo.Since the matchup between Rhodes and Femi generated a lot of excitement among fans, the wrestling universe might still want to see the two champions share the ring again.#1. WWE could book Rhodes vs. Femi for the Undisputed WWE and NXT championshipsIf the above scenario plays out, the Stamford-based promotion might consider making the rematch between Cody Rhodes and Oba Femi more exciting by having the Undisputed WWE and NXT championships on the line.The American Nightmare has yet to hold the NXT Championship, while Oba Femi has yet to lift the Undisputed WWE Championship. Therefore, having both titles on the line could create a blockbuster rematch.
