LOUISVILLE, Ky. (WHAS11) – A firefighter was taken to the hospital after suffering an injury during a house fire in the Portland neighborhood Monday.

MetroSafe reported the fire happening at a vacant home in the 2700 block of Bank Street around 7:30 p.m.

Firefighters on scene told WHAS 11 News there was no one inside the home, but a firefighter was sent to the hospital, injured while working on the outside of the house

"He had fell and hit his forehead and cut it open," Lt. Col. Jim Frederick with the Louisville Fire Department explained.

Lt. Col. Frederick says he is unaware of that fire Fighter's condition. A stairwell also collapsed while firefighters were inside the home, but no one was hurt from that.

"It's rare but it's also expected and we have protocols that we follow in situations like that and we ensure our attention is placed to those members making sure that they're assisted out," said Frederick.

Fire investigators are still trying to figure out the cause but said the fire did start on the bottom floor and work its way up.
