The Dolphins got a healthy quarterback under contract Tuesday. Restricted free agent Cleo Lemon signed a one-year deal for $1.3 million. Lemon is the only uninjured quarterback with playing experience signed by Miami for the 2007 season. Daunte Culpepper still is rehabbing his right knee, second-round pick John Beck doesn't have a contract offer, and Gibran Hamdan is a long shot to stick with the team.
