An entrance collapsed at the WinStar World Casino and Resort.

Over a dozen Backstreet Boys fans were injured when a storm caused an entrance to collapse at an Oklahoma venue.

Per The Associated Press, the WinStar World Casino and Resort said in a statement that the resort began an evacuation early Saturday evening when lightning was spotted a few miles away.

The statement said 150 attendees had not evacuated when winds as strong as 80 mph knocked over trusses, causing the entrance to collapse on top of them.

Fourteen people were reportedly taken to a hospital. 

The Backstreet Boys were slated to perform at the Thackerville casino along with fellow '90s favorite 98 Degrees.

In a statement on Twitter, the Backstreet Boys said fan safety was a top concern for the boy band. 

"We never want to put our fans in harm's way and with tonight’s weather and the injuries from earlier, we have decided to cancel the show and will attempt to reschedule, the statement read. "The most important thing is for everyone to get home safely and we will see you all very soon!"

Earlier in the day, Backstreet Boy member Kevin Richardson tweeted that the concert had sold out to a crowd of 12,000 fans.
