Honolulu EMS responded to a possible shark bite Saturday morning.
However, it may not have been a shark bite after all.
The 48-year-old man who was injured while surfing at Oneula Beach on Oahu on Saturday, told the State Department of Land and Natural Resources Tuesday that he now believes his injury was caused by a surfboard fin.
The patient was said to be surfing when he felt the bite Saturday.

Paramedics treated the patient's lower left leg for a possible bite.
