The incident happened just before 6 p.m. last Saturday when callers to 911 reported a 45-year-old man had broken his ankle at the popular but illegal spot where people jump into the ocean in the 1100 block of Sunset Cliffs Boulevard.
Responding emergency crews found the man at water's edge at the furthest point from the parking lot being attended to by a trio of companions.
Paramedics placed a protective device around the victim's lower leg before loading him onto a backboard and carrying him to a gurney and waiting ambulance.
Medication to reduce the man's intense pain was administered at the scene before he was transported to UCSD Hospital.
When lifeguards attempted to learn how the injury occurred, the trio all denied seeing their friend fall however one insisted the victim slipped and did not jump from the cliff.
