WWE and UFC will be going head-to-head for the first time ever in the same city this Saturday (December 4) in Las Vegas. WWE will be running a house show consisting of both Raw and Smackdown stars at the new Orleans Arena (WWE has always run the Thomas & Mack Center for years) featuring WWE Champion The Miz, Rey Mysterio, Edge, Wade Barrett, Alberto Del Rio and more. UFC will be holding a smaller event at The Palms Casino Resort, “The Ultimate Figher Finale”, to determine the winners of the Team GSP vs. Team Koscheck season. The Orleans area where WWE is running can hold up to 7,000, while The Palms can hold around 2,100 if it sells out.
