It appears increasingly unlikely that quarterback Matt Hasselbeck will be back with the Seattle Seahawks, sources said Tuesday, but the Tennessee Titans will be aggressive in their pursuit of the 13-year veteran.
The San Francisco 49ers and Minnesota Vikings also are interested in Hasselbeck's services, but the Titans are considered the front-runners.
Those aren't the only teams courting Hasselbeck. The Miami Heraldreported Tuesday via Twitter that the Dolphins have "extended interest" in signing Hasselbeck to compete with Chad Henne.
The Seahawks have agreed to terms with quarterback Tarvaris Jackson, reuniting him with Darrell Bevell, his offensive coordinator in Minnesota. Seattle also is expected to sign Matt Leinart, coach Pete Carroll's former quarterback at USC, to join Charlie Whitehurst on the roster.
The Seahawks also are making a play for free-agent wide receiver Sidney Rice, who played for Bevell in Minnesota.
