ECOLA STATE PARK, ORE. - A Portland man was bitten by a shark on the Oregon Coast Monday afternoon, police said.
The attack occurred at Indian Beach at Ecola State Park, north of Cannon Beach.
The victim, 29-year-old Joseph Tanner, was surfing when the shark bit his upper and lower thigh.
Tanner told responders that the shark was "medium-big" and he thought it might have been a great white shark but he wasn't sure.
