Marvin Harrison, now a free agent, said he has no plans to retire and that he wants to play in 2009, according to his agent, Tom Condon. The problematic knee that has limited some of Harrison?s speed and overall effectiveness the past two seasons hasn?t been an issue either, Condon said. ?I played in 15 games last year and a playoff game, and I intend to play again this season,? Condon said Harrison told him in a conversation Thursday afternoon.
