Chicago police say the man fell around 4:55 p.m. Sunday during the NFL matchup between the Bears and the Philadelphia Eagles. He was pronounced dead at a local hospital.
Chicago Fire Chief Joe Roccasalva says the man landed on a small rooftop on the outside of the stadium. Witnesses told authorities the man ran to a ledge and jumped. Roccasalva says the man was in his 20s, but his name hasn't been released.
It's the second death in a week at a major sporting arena. On Nov. 21, a 2-year-old boy fell from a luxury box at the Staples Center during a Los Angeles Lakers game.
