Following the Broncos’ failed fake field goal try, the Raiders took over at their own 36-yard line with just more than three minutes left in the first half.
Three Darren McFadden touches and an 8-yard completion to fullback Marcel Reese put Oakland at midfield.
Defensive end Elvis Dumverfil hit quarterback Carson Palmer on consecutive plays, but Palmer still completed both passes.
From there, Carson Palmer hit wide receiver Denarius Moore for a 37-yard pickup, moving the Oakland offense to the 13-yard line.
McFadden carried the ball the next two plays to pick up a total of 7 yards, leading to an Oakland third-down play which ended in an incomplete pass with tight coverage from safety Mike Adams, bringing out Sebastian Janikowski for his second field goal attempt of the game.
Janikowski converted on the 24-yard attempt inside the final minute of the half, bringing the Raiders to within four points by a score of 10-6.
Peyton Manning kneeled the ball to end the half.
Willis McGahee leads all ballcarries with 40 yards rushing on eight carries. He also has four catches, tied for a game-high, for 17 yards.
Both quarterbacks had strong halves. Manning has thrown only five incompletions on 22 attempts, totaling 196 passing yards and a touchdown. Seven Broncos caught a pass in the first half.
Carson Palmer was 9-of-13 in the half for 142 yards.
The Denver defense held McFadden to 23 yards rushing on nine carries and also limited the Oakland offense to 1-of-6 on third-down plays, while the Broncos were 4-of-8 on third down.
The Raiders will receive to open the second half.
