UFC middleweight champion Anderson “The Spider” Silva will put his 12-fight winning streak and title on the line when he faces top-ranked challenger Chael Sonnen in UFC 117 in Oakland, Calif., on Aug. 7.

The 35-year-old Silva (26-4) has held the title since October 2006, and his string of consecutive victories is not only the longest active streak in the Ultimate Fighting Championship but also the longest streak in UFC history.

Sonnen, 33, is 26-10-1 and was an All-American wrestler at the University of Oregon. His grappling skills have some experts believing he can take the title away from Silva, who was ripped by fans and UFC President Dana White after his last fight, on April 10, for his lack of aggression in the ring.

The undercard also has some intriguing matchups, with veteran welterweights Jon Fitch (25-3) and Thiago Alves (22-5) engaging in a long-awaited rematch after Fitch’s 2006 victory. Hall of Famer Matt Hughes (45-7), who has the most wins in UFC history, will take on Ricardo Almeida (12-3) in a welterweight bout; and Las Vegas-based heavyweight Roy Nelson (16-4) will fight Junior Dos Santos (11-1).
