Burning Man has since released this statement regarding the incident.
The inferno is one of the highlights of the festival, which takes place in the Black Rock Desert in Nevada, drawing crowds of 70,000 from all over the world.
"People try to run into the fire as part of their spiritual portion of Burning Man", Allen said.
Black Rock City firefighters and other rescue crews chased the man after he broke through a safety perimeter and headed for the flames of one the burning sculptures at about 10:30 p.m. Saturday, according to a statement from the festival organizers.
As of this morning, Pershing County Sheriff Jerry Allen confirmed that man had died from his injuries.

The festival was briefly hampered when a lightning-sparked wildfire temporarily shut down Burning Man's main travel route last week.
