Marlin Jackson, a former starter for the Indianapolis Colts, became the first free-agent visit for the Ravens this offseason, but he might not be the team's first free-agent signing.
A league source said said it would be "surprising" if anything happened with Jackson.
Jackson has finished the past two seasons on injured reserve. He was not tendered by the Colts, which made him a free agent.
Jackson is in town because for the Ed Block awards dinner.
