Smith-Schuster (knee) didn't practice Wednesday.
Smith-Schuster also sat out last Wednesday's practice before returning to a full session Thursday. He then proceeded to play 59 of the Steelers' 65 offensive snaps in the team's Week 2 win over the Broncos, hauling in seven of eight targets for 48 yards. If he follows last week's pattern and advances to full participation in practice this Thursday, he'll be on track to play this weekend against the Texans.
