Just prior to the end of the first brand split, a storyline saw CM Punk vowing to leave the company with the WWE Championship when his contract expired on July 17, 2011, the date of the 2011 Money in the Bank pay-per-view. At the event, Punk succeeded in defeating the defending champion John Cena to win the title, and left the company with the physical championship belt. Subsequently, the championship was vacated and Rey Mysterio won an eight-man tournament by defeating The Miz in the finals to be crowned the new WWE Champion, only to subsequently lose it later that night to Cena, for the latter's record ninth reign. However, following Cena's win, Punk returned to WWE with his own championship belt, disputing Cena's claim to the title. The two WWE Champions wrestled each other at SummerSlam; Punk defeated Cena to solidify his claim on the title.
