Firefighters in New Jersey rescued a construction worker on Wednesday after he fell into a nine-foot-deep trench being dug out for a septic tank, authorities said.

The 55-year-old worker was helping dig a trench for a septic system in a residential backyard in Mount Laurel just before 11:30 a.m. when dirt being removed by an excavator hit him in the head, Mount Laurel Fire Department said.
