Per Tom James, CBS and the Trib-Star correspondent:
Wednesday participation: Out -- QB Peyton Manning (neck), LB Ernie Sims (knee) DNP -- LB Gary Brackett (shoulder), S Melvin Bullitt (shoulder), TE Dallas Clark (foot), DT Eric Foster(hamstring), DE Dwight Freeney (abdominal), OG Ryan Diem (ankle), DE Robert Mathis (chest), DT Fili Moala (ankle), TE Jacob Tamme (concussion) Limited -- QB Kerry Collins (shoulder) Full -- TE Brody Eldridge (knee), WR Blair White (back).
And so the injury madness begins. The only ones that look to be somewhat serious are Fili Moala (out for most of Sunday's game), Melvin Bullitt, Ryan Diem, Gary Brackett, and Jacob Tamme.
I expect the rest to play on Sunday against the Steelers, although I would not be surprised to see some of them sit. We just don't have a lot of information on them right now.
