At Night of Champions, every championship will be on the line on the same night. For the tag team championships, it is the only times all night in which two belts, not one, are up for grabs.
Since Night of Champions was born as a part of Vengeance in 2007, there have been seven tag team title matches, the most of any division in WWE. Keep in mind that in 2007 and 2008, there were two sets of tag team championship belts.
In 2009, the WWE Tag Team Championships and World Tag Team Championships were unified and replaced with new belts in 2010.
The eighth instance of a tag team title match in Night of Champions history will occur on Sunday as current champions R-Truth and Kofi Kingston will take on the unlikely duo of Daniel Bryan and Kane.
In the previous seven title matches, only twice has there been a title change. That number rises to three if you consider that Chris Jericho got a new partner to retain his title in 2009.
The advantage is with the champions, who were actually on opposing teams in a WWE Tag Team Championship match at last year's Night of Champions.
In preparation for the latest title bouts, here is a power ranking of all seven tag team championship matches in Night of Champions history.
