Excerpts from cbsnewschicago.com:

A Chicago firefighter is hospitalized after battling a fire at a two-story home near 107th Street and South Indiana Avenue in the Roseland neighborhood Saturday afternoon. 

When firefighters arrived, flames were venting through the roof. Firefighters then began breaking windows on the second floor to provide ventilation. Then there was heavy smoke pouring from the second floor before the roof collapsed. 

The firefighter who was injured was taken to the hospital in good condition and is expected to be OK.  It is unclear how that firefighter was injured and if it was a result of the roof collapse. 

The cause of the fire is under investigation.
