There are four weeks left in the 2012 NFL regular season, and a few teams have already clinched playoff spots.

Peyton Manning and the Denver Broncos clinched the AFC West with their win on Sunday. With a postseason spot already in hand, they will open up the Week 14 schedule.

Denver will visit the Oakland Raiders on Thursday Night Football. On the road, the Broncos are giving the Raiders 10 points, who might be playing as poorly as any team in football. Oakland has lost five straight games by an average of 18.6 points per game.

The Atlanta Falcons and New England Patriots have also locked up their divisions. Both teams are 3.5-point favorites, but are set to face to very different opponents.

Atlanta will visit the Carolina Panthers, who are tied for the worst record in the NFC. New England is set to host the Houston Texans on Monday. A win for the Texans would all but guarantee them home-field advantage throughout the playoffs.

While three division champs have already been decided, three other divisions may come down to the wire.

The New York Giants and San Francisco 49ers hold just a one game and 1.5 game lead, respectively, in the NFC East and NFC West. Both teams were upset in Week 13 and are favorites again this week.

The Seattle Seahawks are looking to surprise a lot of people and top the 49ers in the division. They are the biggest favorites of the week, giving 10.5 points to the Arizona Cardinals. The Cardinals are coming off a loss to the New York Jets in which they were unable to score a touchdown.

The Packers and Bears are tied with 8-4 records atop the NFC North. Green Bay is a 6.5-point favorite against the Lions on Sunday Night Football. The Vikings are three-point underdogs at home to the Bears.

The Redskins and Ravens are expected to have the closest contest of the week. Robert Griffin III’s squad is a 2.5-point favorite in Washington.

The uncertain status of Ben Roethlisberger hasn’t allowed the Las Vegas casinos to make a betting line for the matchup between the Steelers and Chargers. If the quarterback doesn’t return from his injury, Charlie Batch will get the start for another game.

Below are the complete betting lines for all the Week 14 games, including the point spreads and totals. These are the consensus odds from multiple sportsbooks in Las Vegas.
