Ravens running back Jamal Lewis confirmed yesterday that he had surgery a week ago to remove bone spurs from his right ankle and that those bone spurs slowed him during the 2006 season, especially in the first six games until he took injections to ease the pain. Ravens general manager Ozzie Newsome first spoke about the surgery yesterday at the Ravens' annual season-ending news conference. Later in the day, Lewis said from his home in Atlanta that he has a splint on the ankle and that it could be removed as early as today. He expects to start jogging in another one to two weeks and running again in seven weeks.
