Benson Henderson, Nate Diaz Hit Marks for UFC on Fox 5 Lightweight Title Headliner

Henderson tipped the scales at 154.6 pounds for his five-round confrontation with “The Ultimate Fighter” Season 5 winner Nate Diaz (*155) in the UFC on Fox 5 main event this Saturday at the Key Arena in Seattle. The six other fighters called to duty on the main card, including light heavyweight co-headliners Alexander Gustafsson (205.4) and Mauricio Rua (205), also met their contracted weight requirements without issue at Friday’s official weigh-in.

A Brazilian jiu-jitsu brown belt under Royce Gracie protégé John Crouch, Henderson has compiled a perfect 5-0 mark since joining the UFC as part of the World Extreme Cagefighting merger. The 29-year-old MMA Lab representative last appeared at UFC 150 in August, when he eked out a split verdict over former champion Frankie Edgar in their rematch at the Pepsi Center in Denver. Henderson has won 15 of his past 16 fights.

Diaz last competed at UFC on Fox 3 in May, when he coaxed a tapout from the rugged Jim Miller with a second-round guillotine choke at the Izod Center in East Rutherford, N.J., becoming the first man to ever submit the AMA Fight Club mainstay. A Brazilian jiu-jitsu black belt under Cesar Gracie, he owns an 11-5 record inside the Octagon and has pieced together a three-fight winning streak since returning to the 155-pound division. Diaz has secured 14 of his 16 career victories by knockout, technical knockout or submission. However, the 27-year-old Stockton, Calif., native is just 2-6 in fights that reach the judges.
