Injury interpretation as Week 3 games approach:
If Dawson is out, the Colts would have lost their two starting interior linemen in two weeks -- Ed Johnson was cut before the second game because he got in trouble off the field. It's hard to imagine the Colts without Sanders, Johnson and Dawson. In such a scenario, Raheem Brock would surely shift inside from end.
Giordano is the lone backup safety on the roster with Melvin Bullitt filling in for Bob Sanders (ankle/ knee). Look for the team to promote Jamie Silva from the practice squad, but it's unknown where they'd gain the roster spot.
WR Troy Williamson (thigh) is out, but Jerry Porter (hamstring) is questionable. Jack Del Rio said Friday that Porter is not likely to play. If he doesn't, look for him to be designated as the team's third quarterback for a second week in a row. If David Garrard and Cleo Lemon both get hurt, Matt Jones shifts under center and Porter might be able to help a unit without Jones.
LB Colin Allred (ankle), a key special-teamer, is also questionable and a game-time decision.
