Portland Firefighters were called to a house fire Saturday morning near Southeast 89th and Division Street.
When they arrived they found heavy fire coming from the home.
They didn't know whether anyone was inside, so firefighters went in to search.
A portion of the home collapsed minutes later, injuring two firefighters. Both were treated and transported to the hospital with minor injuries.
Firefighters also had to work around downed power lines, which can be deadly upon impact.
No one was home at the time of the fire and a fire investigator is on scene to determine a cause and damage assessment.
