ESPN.com’s Paul Kuharsky is reporting that the Titans may have some interest in recently released wide out Glenn Martinez or possibly Chad Jackson.  Martinez was relased by the Broncos, Jackson, who talked to the Raiders today, was let go by New England.  Kuharsky said that he talked to Jackson’s agent, who said that a couple of other teams were a little more aggressive when it came to wanting his client’s services.  As for Martinez, Titans offensive coordinator Mike Heimerdinger was a Broncos assistant last year, so he is aware of what Martinez can do.
