A guardsman from the 253rd New Jersey National Guard was seriously injured in an accident at the Cape May Court House armory along the Garden State Parkway on Sunday afternoon.

Middle Township police said a military truck backing into a garage struck a partially open garage door.

The door collapsed onto the reservist. The man, whom police have not yet identified, sustained a head injury and was flown to AtlantiCare Regional Medical Center, City Campus.

His condition was not released early Monday.
