Marvin Harrison (knee), Joseph Addai (shoulder), and Bob Sanders (ribs) didn't practice for the Colts at all this week, including Friday. They are all officially listed as questionable for Week 5.
Addai was present for the media portions of practice all week, so he appears to have the best chance to play of the group, though the Indianapolis Star thinks he will probably sit. Sanders is apparently the least likely, with Harrison a close second. The Colts play in an afternoon game. Addai is worth waiting for, especially for owners with both Addai and Kenton Keith, while the others shouldn't be counted on.
We still should be able to beat the Bucs at home without them, but it's going to be a tough game without these gamers.
