The next night on "Raw", Vince McMahon granted Reigns a title rematch against Sheamus, under the stipulation that if Reigns lost, he would be forced to retire. Reigns managed to win after overcoming interferences from McMahon, Del Rio and Rusev, regaining the WWE World Heavyweight Championship in the process. McMahon then forced Reigns to defend his title in the 2016 Royal Rumble match on January 24. In the match, Reigns was eliminated by Triple H, who eventually went on to win the match, thus losing the championship. At Fastlane on February 22, Reigns defeated Brock Lesnar and Dean Ambrose in a triple threat match to receive a WWE World Heavyweight Championship match against Triple H at WrestleMania 32 on April 3, where he defeated Triple H in the main event to become the WWE World Heavyweight Champion for a third time. After WrestleMania, Reigns began a feud with AJ Styles and successfully defended the championship against him at Payback on May 1 and then again at Extreme Rules in an Extreme Rules match later that month. After the latter match, Reigns was attacked by a returning Seth Rollins.
