Mike Goodson then made the ill-advised decision to return a kick from 8 yards deep in the end zone, forcing Oakland to start a drive at their 8. Von Miller then beat Khalif Barnes for a sack on third down, stripping the ball from Palmer. Mitch Unrein recovered at the 2 and Moreno scored two plays later to make it 23-7.
Moreno is filling in for the injured Willis McGahee and is giving the Broncos the running game they will need to be successful in the postseason.
"You always have to have your mind ready to carry it as many times as they need," Moreno said. "That's what we needed. It felt good. It felt good for this offense, you know all the hard work that we do put in."
Prater added another field goal later in the third quarter and Manning went on to his record 12th season with 10 wins as a starting quarterback.
The only remaining drama was whether quarterback project Terrelle Pryor would get his first action of the season for Oakland. He didn't, giving the frustrated Raiders fans yet another reason to be upset even though Palmer added a 56-yard TD pass to Darrius Heyward-Bey and finished with 273 yards passing.
"To rack up this many losses in a row in the fashion that we've done is just extremely frustrating," Palmer said.
After the game police said a man fell from the upper deck at the stadium shortly before kickoff and was in serious condition at a hospital. Initial reports called the fall an accident, but police said it remained under investigation. The team had no comment.
