Story highlights The man was walking with his brother when he fell on Sunday

Witnesses tell police that the man appeared to be intoxicated

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 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.
