NFL Network's Jason LaCanfora hears that free agent Clinton Portis had a "strong" workout for the Titans on Tuesday. "Ran well and could be signed in next week or so," says LaCanfora. We'd advise skepticism, as the report could be agent-driven. The Titans are "monitoring" Javon Ringer's back this week. Portis would only be signed as backup insurance if Ringer's back tightens up again.
