Alberto Del Rio
On the October 26 episode of "Raw", Reigns defeated Alberto Del Rio, Dolph Ziggler and Kevin Owens in a fatal four way to become the number one contender for the WWE World Heavyweight Championship. However, champion Seth Rollins legitimately injured his knee on November 4 and vacated the title the following day, which led to a tournament to crown a new champion. Reigns defeated Big Show in the first round, Cesaro in the quarterfinals, Alberto Del Rio in the semifinals and Dean Ambrose in the finals at Survivor Series on November 22 to win the WWE World Heavyweight Championship for the first time. Immediately afterward, Sheamus cashed in his Money in the Bank contract and defeated Reigns, thus ending Reigns' reign at only 5 minutes. On December 13, Reigns failed to regain the title from Sheamus in a Tables, Ladders and Chairs match at following interference by The League of Nations (Alberto Del Rio and Rusev). After the match, he attacked Triple H in anger.
