The firefighters were called to a one-car crash on Almonesson Road in Deptford Township, around three o'clock Saturday morning.
The car had rolled over and was partially submerged in Timber Creek. Firefighters used ladders, flashlights and other equipment to try and get to the trapped driver.
While the firefighters were trying to free the driver, the car slid and trapped the legs of two of the firefighters. Fellow firefighters scrambled to free their legs and get them to treatment. Investigators say the firefighters suffered minor injuries.
The driver was pulled from the wreckage nearly two hours after the crash happened. The condition of the driver has not been released. Police continue to investigate the wreck.
