ECOLA STATE PARK, Ore. – A Portland man was bitten by a shark on the Oregon Coast Monday afternoon, police said.
The attack occurred around 4 p.m. at Indian Beach, a popular surfing spot 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.
The shark pulled Tanner off his surfboard and he swam to shore, police said. He was airlifted to Legacy Emanuel hospital in Portland with serious injuries.

Jeff Rose, who witnessed the commotion on the beach, said Tanner is a trauma nurse.
"He directed his own first aid, what needed to be done, he asked us a lot of questions, what we were seeing, if we saw spurting blood," said Rose.
Rose said Tanner was sitting on his board when he was attacked.
"He saw splashing, at that point Joe jumped on his board and yelled over (to) get the freak out of here," said Rose.
Rose said a friend of his saw a shark attack a seal in the same area about three months ago.
There are 16 species of shark found along the Oregon Coast, including great white sharks. There have been 27 shark attacks in Oregon since 1974. No one died.
