Undertaker destroyed Cena on his WrestleMania comeback last April in just three minutes following weeks of uncertainty regarding his fitness.
There has been wild speculation over the past few months that the two WWE legends will return to the ring at SummerSlam on August 19.
According to Cageside Seats, Taker is much more likely to come back for the legendary Pay-Per-View than the 16-time world champion.
That makes sense as the seven-time world champion is scheduled to have one more match on Saturday, July 7 at Madison Square Garden as part of the WWE Live SummerSlam Heatwave Tour.
Cena has embarked on a career in Hollywood that has seen him taking part in various blockbuster hits like Trainwreck, Blockers and Ferdinand.
The ex-WWE Champion has also performed alongside some of the biggest celebrities in the industry, such as Will Ferrell, Mark Wahlberg and Amy Schumer.
As a result, he has turned into a part-time performer in WWE and therefore has very limited time available to wrestle.
Undertaker makes very rare appearances for WWE due to a raft of injuries suffered throughout his illustrious 28-year career.
Undertaker and Cena’s last bout took place in April at the Greatest Royal Rumble in Jeddah, Saudi Arabia.
Taker destroyed Rusev in a Casket Match whereas The Champ picked up another win over his former rival Triple H.
