Giddy Packers fans poured into the frigid Lambeau Field parking lots in Green Bay early Tuesday to fire up their grills and throw down beers in a final tailgate to cap a magical season.

At $5 each, the 50,000 tickets for Tuesday's "Return to Titletown" celebration at the stadium sold out in a matter of hours Monday despite 3-degree temperatures and a wind chill that equated to minus-14.

Schools let out early and businesses closed so that fans young and old could pack city sidewalks to cheer the team's returning motorcade.

Tuesday's cold didn't bother Ken Hampp, 23, of Appleton, Wis., as he sipped a beer.

"The weather's fine. I can barely feel it," he said. "That's my favorite thing about winter. You can just stick your beer in the snow."

Shave that thing. Brett Keisel says it's time to move past "Fear the Beard."

Much to the disappointment of the bushy growth's nearly 30,000 Facebook fans, it's time to "Shear the Beard."

The defensive end had promised not to cut or trim the reddish-brown "mountain-man" beard as long as the Steelers kept winning.

Vegas wins - barely. Sports books in Nevada won just $724,000 from Super Bowl bets, despite heavy gambling on victorious Green Bay and lots of scoring.

The Nevada Gaming Control Board said $87.5 million was wagered in 183 sports books across the state, and casinos kept less than 1 percent.

"I can't say I've got a cheese head in my office right now," said Jay Kornegay, executive director of the race and sports book at the Las Vegas Hilton.

Casinos have lost only once on the Super Bowl in the last 10 years. That occurred in 2008, when bettors gambled $92 million and casinos lost $2.57 million as the New York Giants upset New England, 17-14.

Seatless fans get option. The NFL has added a second option for the roughly 400 fans who had to give up their seats at the Super Bowl: They can choose to attend any future Super Bowl instead of being limited to the 2012 game.

Titans fire Heimerdinger. New Titans head coach Mike Munchak fired offensive coordinator Mike Heimerdinger along with two other assistants, a day after taking over the top job.

Heimerdinger, who is continuing cancer treatment since his diagnosis in November, confirmed he had been fired.

The Titans later released a statement saying Munchak told defensive assistant Rayna Stewart and offensive assistant Richie Wessman they would not be retained.

Senior executive vice president Steve Underwood said the team would honor Heimerdinger's contract, which extends through the 2011 season.

Munchak has eight openings to fill. Former teammate Bruce Matthews, now an assistant in Houston, is expected to be Munchak's top target to fill his old job with the offensive line.

Jurisprudence. The Minnesota Court of Appeals ruled there is no legal reason to grant Vikings defensive tackles Kevin Williams and Pat Williams permanent relief from their NFL suspensions for violating the league's anti-doping policy.

Barring another appeal, the ruling appears to clear the way for the NFL to suspend the players, which it has been trying to do since both tested positive for a banned diuretic in 2008.

Noteworthy. New Orleans coach Sean Payton said he would relocate his family to Dallas, and the Saints say the club has given the coach its blessing to do what he thinks is right for his wife and two children. Payton said he and his family have dreamed of settling in Dallas for some time. . . . Tampa Bay hired three assistants, including former Vikings and Eagles defensive tackle Keith Millard. Millard and Grady Stretz will serve as co-defensive line coaches. Tyrone Pettaway was hired as defensive quality control coach. . . . Oakland promoted former player Greg Biekert from defensive assistant to linebackers coach. Biekert is best known for recovering the fumble by Tom Brady that was eventually overturned by replay in the "Tuck Game" against New England in the 2001 playoffs.
