In an amazing feat of endurance, former Miami Dolphins running back Rob Konrad made it safely ashore in Palm Beach after falling off his fishing boat in the ocean late Wednesday night, and swimming for nine miles.According to the Coast Guard, they searched for Konrad after he didn't return from a fishing trip.Konrad told them he was idling in his fishing boat, caught a fish, and while trying to land it, fell off the boat.The boat kept going and Konrad started swimming in the cold, dark ocean.More than 10 hours later, he made it ashore in Palm Beach, and walked up to the oceanfront mansion of the late Palm Beach attorney Robert Montgomery, where he told a police officer what happened.A source said Konrad was barefoot and wearing only his underwear at the time. He was taken to a hospital and treated for signs of hypothermia.He told police that he saw the Coast Guard helicopter's search light go past him in the ocean, but the spotters didn't see him.Calls to Konrad's financial consulting business were not returned.Konrad lives in Boynton Beach.
