A brush fire broke out in a Sabre Springs-area canyon on Tuesday, burning close to streets and homes for a time but causing no structural damage.
The blaze erupted for unknown reasons about 12:30 p.m. near several intersecting footpaths in an open area off Poway Road and Sabre Springs Parkway, according to the San Diego Fire-Rescue Department.
It took ground crews and personnel aboard two water-dropping helicopters about 90 minutes to fully subdue the flames, which blackened "a little more than an acre," SDFRD spokesman Jose Ysea said.
Medics took one of the firefighters to Sharp Memorial Hospital for treatment of a knee injury suffered while helping douse the blaze.
The cause of the fire is under investigation, the spokesman said.
