Police have said a man was critically hurt in a fall at a Grateful Dead concert at Chicago's Soldier Field.
Police said they were called around 9pm on Sunday after a 41-year-old man fell at least 20 feet from a railing where he was sitting inside the stadium. Police said it appeared to be an accident.
The man was taken to a nearby hospital in critical condition. Police said that his condition had stabilised.
The band played three shows over the holiday weekend and Sunday's gig was their last ever performance.
