Three touchdowns from Knowshon Moreno have helped the Denver Broncos overcome a spirited Jacksonville Jaguars tonight, maintaining their 100% record with a 35-19 victory.

Denver looked to be cruising early on as Peyton Manning wasted little time finding his range, throwing touchdown passes to Julius Thomas and Wes Welker in the first quarter.

Jacksonville went into the clash as the biggest betting underdogs in NFL history but scored 12 unanswered points in the second quarter, with two Josh Scobee field goals followed by a 59-yard interception return from Paul Posluszny.

Moreno and Maurice Jones-Drew then swapped scores to keep the Jaguars in touch at 21-19, but Denver's class told late on to keep home fans happy.

Further scores from Moreno eventually proved the difference as the Broncos built momentum up the middle, with the running back continuing his resurgence by completing his hat-trick early in the fourth quarter.

Jacksonville had no answer as their search for a first win of the season goes on, while Denver stretch their perfect record to 6-0.
