(CNN) -- A 30-year-old man died Sunday after falling from a walkway at Candlestick Park during the San Francisco 49ers first regular season game against the Green Bay Packers, police said.
The man was walking with his brother on an elevated pedestrian walkway when he fell onto the sidewalk below.
"Multiple independent witnesses indicated he appeared to be intoxicated prior to his fall," according to a news release from the San Francisco police.
The man's name has not been released.
The incident is one of several recent deaths at large sporting arenas.
In August, a Georgia man fell to his death from an upper level of Atlanta's Turner Field.
In 2012, a Tennessee fan died after falling about 45 feet at the Georgia Dome during a college football game between North Carolina State and the University of Tennessee.
And in 2011, a Texas fan died after falling 20 feet at the Rangers Ballpark in Arlington, Texas, while trying to catch a ball thrown to him by outfielder Josh Hamilton.
