at 3:57 of the second round, becoming the tenth UFC Light Heavyweight Champion. His performance earned him Knockout of the Night honors with a $60,000 bonus for the second time. Machida was expected to face Quinton Jackson in his first title defense, but Jackson opted to coach the tenth season of The Ultimate Fighter instead. Pride Fighting Championship's 2005 Middleweight Grand Prix winner Maurício Rua was then selected as Machida's first title challenger.

In a striking exchange, Rua swerved to avoid a left straight from Machida and landed a powerful counter overhand right to the temple, which knocked Machida down. Rua then took the full mount and proceeded to knock Machida out with ground-and-pound, making him
