The UFC on FOX 4 card continues to grow. The Ultimate Fighter 8 winner Ryan Bader will be taking on former 205lbs. kingpin Lyoto Machida. This fight was not announced as the main event, but a fight of this caliber will most likely end up on the main card, if not the co-main event. UFC on FOX 4 takes place on August 8th, at the Staples Center in Los Angeles and will also feature the promotional debut of Hector Lombard vs. Brian Stann.

Ryan Bader is coming off the biggest win of his career over another former champion in Rampage Jackson. Bader will look for his third win in a row against Machida after coming off an abysmal year where he went 1-2. He lost to current champion Jon Jones by submission, and then lost again by submission to Tito Ortiz. If he is able to beat Lyoto, Bader will be one step closer to a rematch with Jones.

Lyoto on the other hand, will come into this match with something to prove after his latest defeat. At one time Lyoto was thought to be unbeatable, until he ran into Shogun Rua. In the last three years he has went 1-3 with his only win coming over an aging Randy Couture. A win over Bader will put some legitimacy to his career, but the question is will he be able to beat the powerhouse from Arizona.
