Surfers rescue man from drowning at SF's Ocean Beach

Two surfers pulled a man to safety at  Ocean Beach in San Francisco after he was knocked underwater by a huge wave on Sunday.

The man was swept under while using a body board around 9 a.m., according to authorities. 

A woman walking her dog in the Outer Sunset neighborhood saw the wave break over the man. She flagged down the surfers who pulled the man onto the beach and called 911. 

The man has been hospitalized and is expecting to recover, authorities said.
