A surfer across from Patrick Air Force Base's main entrance off state Road A1A suffered an apparent shark bite on Wednesday, witnesses said.

The man, who was not identified, refused treatment.

Jon Humphrey, 33, told Local 6 News partner Florida Today that he and a friend paddled out about 50 to 100 feet off the beach when another surfer near them began shouting, "Shark!"

Humphrey said he looked up and the guy was "punching a shark that was on his foot."

"He got onto the beach and was holding his foot," said Humphrey, who along with his friend grabbed a T-shirt and wrapped the man's foot. He said the wound appeared to be bad enough to require stitches.

The water "blew up" around him, Humphrey said. He slipped off his board and went to shore. Humphrey said the shark appeared to be about 3 feet long.

"I think I'm done here for the day," Humphrey said.
