On Saturday December 12, 2009, UFC lightweight champion BJ Penn will face possibly his toughest test at 155 pounds in the relentless Diego Sanchez at UFC 107: Penn vs. Sanchez, live from FedExForum in Memphis, Tennessee.

“In this sport it sometimes takes years for fighters to find the weight class where they’re at their best,” UFC President Dana White said. “I don’t think there’s any question that BJ Penn and Diego Sanchez have finally found their homes at 155 pounds, making the UFC 107 main event a fight between the best Penn and Sanchez we’ve ever seen. BJ hasn’t lost in this weight class in years, and Diego has looked unstoppable in his lightweight fights, and when these two meet in the center of the Octagon, it’s going to make our first trip to Memphis one fight fans will never forget.”
