Raiders vs. Broncos score update: Denver leads Oakland at halftime, 10-6

The Denver Broncos hold a 10-6 halftime lead over the Oakland Raiders on Sunday at Sports Authority Field at Mile High. Peyton Manning was efficient in leading the Broncos' offense, completing 17 of 22 passes for 196 yards and a touchdown.

Manning found Joel Dreessen for a 22-yard touchdown strike to cap off the Broncos' 11-play, 80-yard opening drive. After that, both teams embarked on long drives that resulted in field goals, with the Broncos taking a 10-3 lead at the end of the first quarter.

The Broncos put together another nice drive midway through the second quarter, but were unable to put points on the board after trying, and failing at, a fake field-goal attempt. That allowed the Raiders to get the football in decent field position, and they answered with a Sebastian Janikowski field goal in the closing seconds of the first half to make it a 10-6 game.

Broncos center J.D. Walton left the game after the play prior to the fake field-goal attempt. He injured his ankle after appearing to have his leg rolled up underneath a Raiders defender. The three-year starter out of Baylor, who has not missed a start in his career, will not return to the game.
