Manning, operating the no-huddle offense, took the Broncos downfield in their first series of the game. His 22-yard completion to Demaryius Thomas gave Denver a first-and-goal at the 4-yard line. Two plays later, Manning hit a wide-open Decker in the end zone on a play-action pass.
Manning's second touchdown toss went to Welker, who shook Porter with an outside move before coming back across the middle to gather in Manning's pass. The play gave the Broncos a 17-0 lead in the middle of the second quarter.
The Raiders broke up Denver's scoring spree with Pryor's long touchdown pass to Moore. The Oakland receiver made the catch at midfield, broke away from two defenders and broke a tackle at the goal line.
Denver came right back as Decker and Manning teamed up on a 61-yard completion to get within striking distance. A couple of plays later, Woodson lined up directly across from Julius Thomas and then blitzed. The tight end slipped out to the flat unguarded, and Manning quickly lofted the ball over the charging Woodson and into Thomas' arms, giving the Broncos a 24-7 lead with 3:40 left in the second quarter.
In the final minute before halftime, Denver's Matt Prater kicked a 41-yard field goal. He made a 53-yarder in the last minute of the first quarter.
