Hundreds of athletes will be without indoor fields after the bubble structure at the Subway Soccer Centre collapsed yesterday.

Around 10:30 a.m., someone driving by reported the structure was deflating, said Brian McAsey of the fire department.

There was one employee in the building at the time but he was uninjured.

“Somehow the atmosphere that’s within there, it lost pressure so what happened was it rapidly, sort of like a balloon, let all the air out,” said McAsey.

McAsey said that one of the seams of the building was torn, which could have contributed to the deflation.
