Pittsburgh ? More than 300,000 black-and-gold bedecked Pittsburgh Steelers fan — about the population of the city itself — packed the streets of “Sixburgh” on Tuesday for a parade celebrating the storied franchise’s unprecedented sixth Super Bowl title.

From infants to senior citizens, fans braved freezing temperatures and crowds so deep that for some even seeing the parade was impossible.

Not that it mattered. Many just wanted to be part of the festive atmosphere and have the chance to revel in the team’s 27-23 victory over the Arizona Cardinals in Sunday’s Super Bowl. Rousing chants of “Here we go Steelers!” pulsed through the crowd as they waited for the team to make its way along the route.

Renaming the city Sixburgh for the day, Pittsburgh Mayor Luke Ravenstahl made his way through the parade alongside quarterback Ben Roethlisberger, both filming the crowd that painted a gray sky yellow with twirling Terrible Towels.

Fans filled parking garages, skyscraper windows, balconies and even climbed trees to get the best view of the team they love and possibly find shelter from the sporadic flurries and temperatures that hovered in the mid-20s.

NFL

Super Bowl most-watched

New York — Upon further review, Nielsen Media Research now says that the Arizona-Pittsburgh Super Bowl game was the most-watched in history. Nielsen said 98.7 million people, on average, were watching Pittsburgh’s exciting 27-23 victory Sunday night. That beats the 97.5 million who watched the 2008 game, which held the record for most popular Super Bowl.

On Monday, Nielsen had reported that this year’s game had 95.4 million viewers — impressive, but not a record-setter.

Chiefs silent on Haley

Kansas City, Mo. — The Kansas City Chiefs aren’t commenting on reports they’ve received permission to talk to Arizona offensive coordinator Todd Haley about their head coaching job.

Haley has been prominently mentioned as the prime candidate for the job since the Chiefs hired Scott Pioli as general manager in January. Head coach Herm Edwards was fired 10 days after Pioli arrived. Pioli and Haley worked together for the New York Jets from 1997 through 1999.

Haley coordinated the offense that helped the Cardinals win the NFC championship and go to their first Super Bowl, which they lost in the final minutes on Sunday to Pittsburgh.

Raiders keeping Cable

Oakland, Calif. — The Oakland Raiders retained head coach Tom Cable on Tuesday, officially removing the interim designation from his title more than five weeks after their season ended.

Cable went 4-8 after replacing Lane Kiffin with the Raiders (5-11), who have lost at least 11 games in six consecutive years.

NBA

Magic’s Nelson sidelined

Orlando, Fla. — All-Star point guard Jameer Nelson could miss the rest of the season for the Orlando Magic because of a torn labrum in his right shoulder.

An MRI exam revealed the injury Tuesday, the team announced. Nelson will decide over the next week whether he will have surgery or attempt rehabilitation. If surgery is the option, his season is likely over. If he passes on the surgery, he’ll likely miss several weeks.

H-O-R-S-E set for weekend

H-O-R-S-E has galloped into the NBA’s All-Star weekend. The popular shooting contest will be part of TNT’s coverage of All-Star Saturday night, the network announced Tuesday. Three NBA players, who will be revealed later, will take part. The competition will take place outdoors at the NBA’s All-Star Block Party in Phoenix on Feb. 14. The dunk contest, three-point shootout and skills challenge are later Saturday night, and the All-Star game is Sunday. Players will have 24 seconds to execute their shots, and an NBA referee will rule if they’re done properly.

RUNNING

Dowell completes stair race

New York — Joining nearly 200 other extreme athletes, Lawrence resident Keith Dowell on Tuesday completed the annual Empire State Building Run-Up, a race up the stairwell of one of the world’s tallest buildings.

Despite running into a bottleneck at the start of the race — runners begin in the lobby of the building, where they must then funnel through a small doorway — the 54-year-old Dowell completed his first Empire State Building run in 16:15 to finish 79th out of 179 runners in the event. He also finished sixth in the 50-60 age group.

“I want to go again next year,” said Dowell, who also competes in various triathlons and road races in the area. “I always want to do better. The first time, you get to know it a little bit. The second time is when you’ve learned a little bit.”

Thomas Dold of Germany and Suzy Walsham of Singapore repeated as winners.
