For the first time since midsummer, the Las Vegas Hotel & Casino sports book doesn’t list the Broncos as the favorites to win Super Bowl XLVIII.

The Seattle Seahawks are the favorites now, with 3-2 odds to win the Super Bowl. The Broncos are second with 5-2 odds.

The Broncos were listed as the prohibitive favorites from training camp until two weeks ago, when they became co-favorites with the Seahawks. Now the Seahawks, who have the NFL’s best record (12-2), are the favorites to win the Super Bowl at the Meadowlands on Feb. 2.

“There are three factors that led to the odds change,” said Jay Kornegay, sports director for the LVH super book. “One, the (Denver) offense didn’t play that well (Thursday) against San Diego. Two, the (Denver) defense is concerning. And three, Seattle has consistently played well.”

The San Francisco 49ers are a distant third with 8-1 odds, followed by New England (12-1), New Orleans (12-1), Cincinnati (12-1) and Carolina (12-1).

Surprisingly, Kansas City (16-1 odds) and Indianapolis (30-1) aren’t getting much love even though they are the only teams besides Seattle and Denver that have clinched a playoff berth.

Injury report. For bonus practice Monday, the Broncos had four players missing: slot receiver Wes Welker (concussion), cornerback Kayvon Webster (fractured thumb), defensive lineman Derek Wolfe (seizure symptoms) and quarterback Peyton Manning (high ankle sprain).

Manning attended the walk-through session and team stretch and was called on to break it down (where players gather in a huddle, string together some collective claps and break off to their position groups). He then left the field with strength and conditioning coach Luke Richesson to go to the weightlifting facility.

Usually, the Broncos only watch film and recover through conditioning on Monday. But because the team had the weekend off, it got in an extra practice. The session was heavy on fundamentals, individual and position drills. Backup QB Brock Osweiler ran the first-team offense.

Denver’s players have Tuesday off and will begin their game-planning practices for the Houston Texans on Wednesday. The Broncos are 11-3 and will capture the AFC’s No. 1 playoff seed if they beat Houston (2-12) and Oakland (4-10) in their final two regular-season games.

“You fall asleep at the wheel and you wreck,” coach John Fox said. “We’re, like I said, rebooting, recharging and they’ll come back Wednesday and we’ll start preparing.”

Special sportsman. Wide receiver Demaryius Thomas summed it up well when asked about Manning receiving Sports Illustrated’s sportsman of the year award.

“I feel like he gets something every week,” Thomas said. “I’m proud of him. He did a great job these past (two) years he’s been with us.”

Footnotes. The Broncos are tied for 18th in the NFL with a minus-3 turnover margin. The only potential playoff teams with worse turnover marks were Baltimore (minus-5) and Detroit (minus-10), who played each other Monday night. … The Broncos and Texans are tied for fourth with 103 penalties. Seattle is the league’s most pen- alized team, with 112.
