DENVER (AP) — Denver’s getting ready to party like it’s 1999.

Hundreds of thousands of people are expected to flood a downtown park and a 1.5-mile-long parade route today to celebrate the Denver Broncos’ first Super Bowl championship in 17 years.

Officials won’t give specific turnout predictions, but the last time Denver won the Super Bowl in 1999, the downtown party drew an estimated 375,000 people. A year before that, when the Broncos won the Super Bowl for the first time, about 650,000 people showed up.

“Were probably expecting hundreds of thousands,” said Mike Stott, a spokesman for Mayor Michael Hancock.

Today’s celebration starts at 10 a.m. with a concert featuring Colorado natives Big Head Todd and The Monsters, 3OH!3 and Funkiphino.

The parade steps off at noon near Union Station, with fire trucks carrying players, coaches and general manager John Elway, who was quarterback the last time the Broncos won.

Hancock and Gov. John Hickenlooper will also be in the parade, which is expected to take an hour to arrive at the City and County Building, where the rally takes place.

Police spokesman Doug Schepman wouldn’t talk about the specifics of security but said plenty of officers will be present. He said the city is in regular contact with state and federal law-enforcement officials but he wouldn’t discuss any conversations they’ve had about today’s events.

Alcohol and — this being Colorado — marijuana will be banned.

Fans began celebrating Sunday night as the clock ticked down on the Broncos’ 24-10 win over the Carolina Panthers in Super Bowl 50.

Scores of fans took to the streets in central Denver in a mostly peaceful but boisterous celebration.

The crowd became unruly at times, but officers for the most part watched from the sidewalk. Police reported a handful of arrests, mainly for criminal mischief.

Ratings

NEW YORK (AP) — Denver’s victory over Carolina in the Super Bowl reached an average of 111.9 million viewers, a number down from the last two years.

Still, it represents the third most-watched television event in U.S. history. The Super Bowl had set viewership records for six of the past seven years.

The Nielsen company said Monday the event was live-streamed by just under 4 million additional people, setting records in the digital space.

Last year’s game between New England and Seattle, which went down to the wire, remains the most-watched Super Bowl ever with 114.4 million viewers.

Lynch to retire

SEATTLE (AP) — Marshawn Lynch intends to retire from football.

Doug Hendrickson, the agent for the Seattle Seahawks star running back, confirmed his client’s plans to The Associated Press on Monday.

Lynch had indicated as much Sunday night by tweeting a picture with a pair of cleats hanging from a power or telephone line, along with an emoji depicting a peace sign. The Seahawks official Twitter account later added the hashtag (hash)ThankYouBeast- Mode to Lynch’s original message. A spokesman said the tweet stood as the team’s comment.

Lynch won a Super Bowl with Seattle and played nine seasons in the NFL. He arrived in Seattle in 2010 and his attitude and bruising running became the foundation for two straight NFC championships and the franchise’s first Super Bowl title.

Manziel troubles

DALLAS (AP) — Johnny Manziel’s ex-girlfriend said in an affidavit the Cleveland Browns quarterback hit her so hard during a late-night confrontation she lost hearing in one ear.

Colleen Crowley’s affidavit, published online Monday, says Manziel dragged her into a car last month after she tried to get away from him. Crowley accused Manziel of striking her in her left ear.

Crowley detailed the alleged attack as part of proceedings to obtain a protective order against Manziel, who is under criminal investigation on allegations of domestic violence.

Manziel, a Heisman Trophy winner whose professional career has been marred by headlines about his drinking and other personal issues, is expected to be cut by the Browns next month.

In the affidavit, first published by TV station KXAS, Crowley said she and Manziel had a confrontation in his hotel room around 1:45 a.m. Jan. 30. Crowley accused Manziel of throwing her onto his bed after the two discussed him “being with a girl who had caused us problems in the past.”

Crowley said she tried to leave, but he restrained her and led her downstairs to the valet, where he directed her to his car. She said the valet disregarded her pleas for help.

Crowley and Manziel eventually made it to her vehicle in front of a Dallas bar, her affidavit says. Manziel allegedly got into the driver’s seat of her car and started to back out of the spot. She said she opened her door and jumped out, trying to hide.

She accused him of chasing her down, throwing her back into the car and hitting her left ear.

“Fearful for my life, I hit (Manziel) several times, hoping I could back out of the car,” she said in the affidavit, adding Manziel “threw me off of him and I hit my head on the car window and I fell into the passenger floorboard.”

Police have said they drove to Fort Worth, where they continued arguing before Manziel fled on foot.

Manziel’s attorney, Bradley Beckworth, did not return a phone message Monday. Crowley’s attorney, Kathy Kinser, declined to comment.

Crowley spoke to Dallas police on Friday, and shortly afterward, authorities announced they were investigating a domestic violence complaint against Manziel.

McCoy troubles

PHILADELPHIA (AP) — Buffalo Bills running back LeSean McCoy is under investigation over the alleged assault of two off-duty police officers at a Philadelphia nightclub.

The incident occurred early Sunday after an argument broke out between McCoy’s party and the officers over a bottle of champagne.

After one 40- year- old officer was knocked to the ground, he was punched, kicked and stomped multiple times on his body and head, police said Monday.

When the second officer, also 40, intervened with security guards, he was also injured, police said. All were ejected from the club.

One officer had a broken nose, broken ribs and a sprained thumb, police said, and the second was hospitalized with a possible skull fracture.

“Certainly over a bottle of champagne, nothing warrants an assault like this,” police Lt. John Stanford said.

A person familiar with the investigation confirmed to The Associated Press that McCoy was one of the four men under investigation. He spoke on condition of anonymity because he was not authorized to publicly discuss the case.

McCoy’s agent, Drew Rosenhaus, didn’t immediately return a message seeking comment Monday. McCoy played for the Bills last season after being traded from the Philadelphia Eagles, where he played for six seasons.

The Bills released a statement saying they were aware of the report and were gathering information.

The two officers did not identify themselves as policemen to their alleged attackers, Stanford said.

The fight over the bottle of champagne appeared to result from a misunderstanding. Stanford said a member of the football players’ party thought a bottle belonged to his group but in fact receipts showed it did not.

According to a police incident report obtained by The Philadelphia Inquirer and KYW-TV, the incident occurred at the Recess Lounge in Philadelphia’s Old City neighborhood.
