Associated Press JOHANNESBURG (AP) Knocked off his board by an attacking shark, three-time world champion Mick Fanning punched the creature before escaping unharmed during the televised finals of a world surfing competition in South Africa on Sunday. The Australian surfer was struck by the shark from behind and knocked into the water as he sat on his board waiting his turn during the JBay Open in Jeffrey's Bay in the Eastern Cape Province. As he scans the water, two fins appear and with a splash he disappears under the surface.
