Miller will be making his season debut after shredding his knee last December. He didn't participate in training camp or the preseason, but was able to avoid the regular season PUP list. The Steelers are desperate for playmakers in the passing game. They will be without running back Le'Veon Bell for at least one more week.
Tillman didn't practice on Wednesday or Thursday and only got in a limited session on Friday. He's been dealing with a knee issue the past two weeks, but was never in any real danger of missing this week's game. There are otherwise no real surprise scratches for the Bears.
Here's the complete inactive list.
WR Marquess Wilson, CB C.J. Wilson, RB Michael Ford, OG James Brown, OT Jonathan Scott, DE David Bass, DT Zach Minter
QB Landry Jones, WR Derek Moye, RB Le'Veon Bell, CB Cortez Allen, CB Isaiah Green, C/G Cody Wallace, DT Hebron Fangupo
