Here's what we know so far:

DOUBTFUL:
T Tony Ugoh

QUESTIONABLE:
T Ryan Diem (ankle)
T Daniel Federkeil (concussion)
TE Bryan Fletcher (calf)
CB Matt Giordano (hamstring)
WR Anthony Gonzalez (hand)
LB Tyjuan Hagler (neck)
WR Marvin Harrison (knee)
CB Daymeion Hughes (shoulder)
CB Tim Jennings (upper leg)
T Charlie Johnson (ankle)
S Bob Sanders (knee)

Nearly everyone listed as questionable was able to practice on Friday, so we'll have to wait until gametime to find out the real story. If Harrison is ready to go, expect Dungy to ease him along with several other big guns back into action.

The Colts also signed offensive tackle Corey Hilliard, a rookie from Oklahoma State to replace Dan Klecko who was waived on Friday. Klecko was a fan favorite from the Super Bowl run last season, but has only 2 tackles in 3 games this year.
