Marvin Harrison returned to practice Wednesday and could play in the Indianapolis Colts' playoff game next week. Harrison has missed a career-high 11 games since bruising his left knee against Denver on Sept. 30. He practiced twice last week but was held out of the regular-season finale against the Tennessee Titans. Indy (13-3) will play the San Diego Chargers, Pittsburgh Steelers, or Jacksonville Jaguars on Jan. 13. "Right now, we don't have anybody who has been ruled out," Coach Tony Dungy said Wednesday. "Marvin practiced today, and he did well. He's not been ruled out. I guess he'll be day-to-day for the next seven days."
