ALAMEDA -- The Raiders appear to be at full strength for the second consecutive practice Thursday in preparation to face the Denver Broncos.

The Raiders switched their usual weekly routine, practicing Tuesday and then taking Christmas off. Ordinarily, the Raiders are off Tuesday and practice Wednesday.

On Tuesday, the Raiders had their first practice of the season during which all 53 men on the roster were healthy enough to participate.

They'll need everyone they can get to stay with the Broncos, who are 12-3 and will go into the game possibly needing a win to secure home field advantage throughout the playoffs.

Denver, with Peyton Manning having thrown an NFL record 51 touchdown passes, has scored 572 points and has five players -- Knowshon Moreno, Demaryius Thomas, Julius Thomas, Eric Decker and Wes Welker -- with 10 touchdowns or more.

The Raiders by contrast, have had two players with 10 touchdowns or more in the last 11 years, Lamont Jordan in 2005 and Darren McFadden in 2010.

``Obviously they're the best team in our division and the best team in our conference right now,'' Raiders coach Dennis Allen said. ``The quarterback may be one of the best players to ever play the game . . . We're going to have to do a great job defensively of keeping the ball in front of us and do a great job of tackling when they throw it underneath.''

Manning is completing 67.4 percent of his passes for 5,211 yards, 51 touchdowns and 10 interceptions for a passer rating of 113.0.

Through Oakland's five-game losing streak against Ryan Fitzgerald, Tony Romo, Geno Smith, Alex Smith and Philip Rivers, the Raiders are have surrendered a 70.5 completion percentage (108-for-153), 1,275 yards, 10 touchdowns and two interceptions for a passer rating of 112.0.
