A man has died after falling from an elevated walkway at San Francisco's Candlestick Park Sunday afternoon during the NFL game between the 49ers and Green Bay Packers.

San Francisco police spokesman Gordon Shyy told the Associated Press that multiple people saw the male fan fall from the Jamestown walkway, which goes around the stadium, onto the sidewalk shortly after kickoff at 1:30 p.m. local time. Witnesses said the man appeared to be intoxicated.

Off-duty medics and police officers gave the man first aid until an ambulance arrived, but the man was later pronounced dead from his injuries.

Shyy said the man appeared to be in his 30s. It was not immediately clear how far he had fallen. The man's identity is being withheld pending notification of next of kin.

In a statement, 49ers spokesman Bob Lange confirmed the team had learned of the accident outside the stadium.

"We would like to express our deepest condolences to the family during this difficult time," he said in an email.

The historic sports complex closes after this season and will be replaced by a shopping center. Next year, the 49ers will move into a $1.2 billion stadium at the team's Silicon Valley headquarters in Santa Clara.

Since 2003, there have been more than two dozen cases of fans falling at stadiums across the United States, according to the Institute for the Study of Sports Incidents.

Most recently in Atlanta, baseball fan Ronald Lee Homer Jr. died last month after falling 85 feet following a tumble over Turner Field's fourth-level railing. Homer's death was the third at an Atlanta stadium in the past year.

Also last month in Denver, Broncos fan Noel Robinson was injured when he fell about 10 feet from an escalator at a preseason game.
