Sebastian Janikowski kicked a 24-yard field goal with 22 seconds left in the half as the Raiders capitalized on a horrific decision by the Broncos and went into halftime trailing by only four points.
The Broncos wasted a scoring opportunity on an ill-advised fake out of field goal formation on fourth-and-1 from the Oakland 36-yard line.
Coming as it did when Manning was 17 of 22 for 196 yards and Willis McGahee was gaining yards on the ground, the idea of having Matt Prater take a pitch from the holder and throw a pass was over-thinking at its best _ or worst.
Oakland took possession, and with Carson Palmer hitting Denarius Moore with a 37-yard pass into Denver 13, had a chance to tie the score.
The Raiders could not make Denver pay in full, however, getting to the 6-yard line with a third-and-3, a drive that ended when Palmer threw incomplete to David Ausberry at the goal line.
