On January 27 at the Royal Rumble kick-off, Nakamura defeated Rusev to win the United States Championship for the second time. Later that night, Nakamura participated in the Royal Rumble match, entering as number 3, but was eliminated by Mustafa Ali. Two days later, on SmackDown, Nakamura lost the title to R-Truth in a rather controversial manner, ending his reign after 2 days. After that, Rusev confronted Truth and encouraged him to have a title match against him, but Truth retained the title. After the match, Nakamura joined forces with Rusev to attack Truth. From that, Nakamura and Rusev began to team up. At the Fastlane kick-off, Nakamura &amp; Rusev were defeated by members of The New Day, Big E &amp; Xavier Woods. At WrestleMania 35, Nakamura &amp; Rusev were defeated by The Usos in a Fatal 4-Way match for the SmackDown Tag Team Championships, which also involved The Bar (Cesaro &amp; Sheamus) and the team of Aleister Black &amp; Ricochet. The duo returned during a 51-Man Battle Royal at the Super Show-Down event, from Jeddah, Saudi Arabia, but were both eliminated during the match.<end_of_turn>
