Veteran tight end Dallas Clark is still absorbing the Ravens' playbook and didn't have a sterling debut Thursday night during a 34-27 preseason loss to the Carolina Panthers. Clark started and was targeted twice for no receptions in his first game for the Ravens since signing a one-year $1.005 million contract. Although Clark didn't appear to be in sync yet with quarterback Joe Flacco they have had solid timing in practice sessions. "I think he had the one seam route that was a little high and would have been a tough grab" Ravens coach John Harbaugh said. "I would have loved to have seen him get a chance but sometimes the coverage just doesn't allow that."
