At a Backstreet Boys in 98 Degrees concert in Oklahoma Saturday night, a strong storm went through the area just before the concert was about to start causing a structure to collapse.
Witnesses say a metal entrance structure holding up a banner, fell.
A spokesperson for the casino that hosted the show said the outdoor venue where the concert was being held was evacuated due to the storm.
But some people standing in line to enter the concert failed to do so.
At least 14 people were hurt.
Backstreet Boys member, Kevin Richardson, commented on Twitter saying the concert was called off due to storm damage.
