Although team officials said this week that Marvin Harrison is making progress in his rehabilitation from a knee injury that has plagued him for nearly two months, the Indianapolis Colts' wide receiver will not play in the Thursday night game here against the Atlanta Falcons. Harrison, in fact, did not even make the trip on the team's Wednesday afternoon charter. This will mark the sixth game that the eight-time Pro Bowler has missed in 2007. Before this season, the 12-year veteran had missed only six games total in his career with never more than four in a season.
