The man fell shortly before 8:55 p.m at the stadium and landed in a secured parking lot.
Atlanta police said the fall appeared to be accidental and added it was too early to tell if alcohol played a factor.
An investigation is underway and police have questioned those who saw what happened.
The game was scheduled to start at 7:10 p.m., but heavy rains pushed back the start time nearly two hours. The fall took place during the rain delay.
It’s the second such death at an Atlanta sporting venue in the last year.
On August 31, a Tennessee fan died after falling about 45 feet at the Georgia Dome during a college football game between North Carolina State and Tennessee.
In July 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.
