Problem:Question: What was Vince McMahon's net worth the year CM Punk fought Ryback in TLC for the WWE Championship? Passage:The major rivalry going into TLC was between the reigning WWE Champion CM Punk and Ryback. Having been denied the title at Hell in the Cell by 'rogue official' Brad Maddox, Ryback along with John Cena competed in a triple threat match for Punk's title at Survivor Series. However, Punk was able to retain the title again when the debuting trio of Dean Ambrose, Seth Rollins, and Roman Reigns interfered and powerbombed Ryback through a table as he was closing in on victory. The trio followed this up by putting Ryback through a table once again the next night on Raw, and, calling themselves The Shield, continued to attack a myriad of superstars over the following weeks including repeated assaults on the WWE Tag Team Champions, Team Hell No, who vowed to put aside the personal differences which had marred their title reign and become united as a result. Having been denied the chance to win the WWE Championship at Survivor Series, Ryback was granted another opportunity at the title in a Tables, Ladders, and Chairs match against Punk. However, the following week during a brawl involving The Shield, Team Hell No and The Miz, Ryback assaulted Punk with a chair and a ladder before powerbombing him through a table. The next day, Punk underwent surgery for a (legit) knee injury, and so was removed from the card. Instead, Ryback would team with Team Hell No against Ambrose, Rollins and Reigns in a six-man tag team TLC match. This match (which was announced via a press release by WWE chairman Vince McMahon) differed from standard TLC matches as it would be decided via pinfall or submission. However, the original TLC match between CM Punk and Ryback was rescheduled to took place on the first Raw of 2013.
