A subcontractor who was working in the Edmonton Eskimos' steam room at Commonwealth Stadium was pulled from the rubble after a section of ceiling collapsed Wednesday afternoon.
The 42-year old man, who worked for a company called Ideal Tile, was replacing tile in the steam room when the sub-roof collapsed around 3:20 p.m.
The man was covered in light concrete rubble but the weight of the heavy debris wasn't resting directly on him, said Deputy Fire Chief John Lamb.
"It's a very small space, probably ten by ten at this point," Lamb said.
The man had to be freed by a fire and rescue crew in a process that took about an hour. He was taken to the Royal Alexandra Hospital and officials said his condition was not yet known.
However, he was conscious and able to speak with paramedics.
City officials said occupational health and safety staff arrived on scene shortly after the incident occurred.
"We are taking this matter seriously," said Joe Kabarchuk, branch manager for building and landscape services in a news release.
"The area was not open to the public at the time of the incident and will remain closed until we complete a full investigation into what occurred."
The locker room was renovated in 2010 and 2011 as part of work done to the practice area and field house. However, Kabarchuk said the sauna area was not part of that renovation.
