DE Dee Ford returned to practice on Friday, which bodes well for his chances of playing on Sunday. Ford left this past weekend's game against the Cincinnati Bengals bothered by the quadriceps and knee injury which plagued him during training camp and forced him to miss the preseason.
The 49ers' other marquee edge rusher, Nick Bosa, has practiced all week after missing most of last week but still playing in Cincinnati. He is listed as questionable.
For the Steelers, RB James Conner (knee) has practiced all week and is expected to play against the 49ers.
Below are the official injury reports for the 49ers and Steelers, which were provided by the 49ers Communications staff. Also included are this week's practice participation reports.
