The Broncos are going to get their first serious look at rookie QB Tim Tebow, who makes his first NFL start with Kyle Orton’s ribs too sore to play. The Broncos have won six of their last seven games here, but the Raiders are still alive in the playoff race and figure to make amends. Raiders RB Darren McFadden is coming off a 123-yard rushing game. He ran for three TDs and 165 yards when the Raiders won at Denver, 59-14. McFadden needs seven rushing yards to become Oakland’s first 1,000-yard rusher since Justin Fargas in 2007. The Broncos are still on track to hire John Elway for a front-office position once the season ends.
