From January until April 2018, Cena was involved in a storyline where he was trying to find his "path to WrestleMania". After he lost the Royal Rumble and the Elimination Chamber match to determine the next number one contender for the Universal Championship at Elimination Chamber, as well as a six-pack challenge at Fastlane for the WWE Championship, Cena issued a challenge to The Undertaker for a match at WrestleMania 34. He reiterated his challenge over the next several weeks, only to receive no answer from Undertaker. At WrestleMania, after Cena drove off Elias in a confrontation, Undertaker made an impromptu return and accepted Cena's challenge, leading to a shocked Cena losing to Undertaker in just two minutes. Three weeks later, at the Greatest Royal Rumble, Cena defeated Triple H. After the match, he thanked the crowd for sticking by him during a tough period, referencing his loss to Undertaker at WrestleMania and his recent breakup with Nikki Bella. He then went on hiatus to focus on his acting and television career. Cena returned in October, competing in a tag team match with Bobby Lashley against Elias and Kevin Owens at Super Show-Down in Melbourne, Australia, which he and Lashley won. During the event, he revealed a controversial new hairstyle, which led to several reactions from fans on the internet. He later said he grew his hair out for a movie he was filming in Yinchuan, China. He was also scheduled for a match at Crown Jewel in Saudi Arabia, but Cena refused to work the event following the murder of Saudi journalist Jamal Khashoggi. On November 29, it was announced Cena had been awarded the Muhammad Ali Legacy Award Winner by "Sports Illustrated".
