Brock Purdy remained limited in Thursday's practice, while Mac Jones returned to full participation.

Purdy is working his way back from a toe injury that has limited him to two games this season. Jones has knee and oblique injuries that he is playing through.

Thursday's practice report indicates Jones will make his fifth start of the season.

"It means he most likely will," coach Kyle Shanahan said of Jones starting, via David Bonilla of 49erswebzone.com. "We'll see how Brock does tomorrow. But yeah, Mac's much better than he was last week, and Brock is doing better than he did last week."

The 49ers play the Falcons on Sunday Night Football.

The 49ers saw defensive tackle Kalia Davis (hand), defensive tackle C.J. West (thumb) and defensive tackle Kevin Givens (pectoral) return to full participation. They were limited on Wednesday.

Wide receiver Skyy Moore (ankle) and offensive guard Dominick Puni (knee) returned to practice with limited participation.

Wide receiver Ricky Pearsall (knee) and defensive end Yetur Gross-Matos (knee, hamstring) remained out of practice. Wide receiver Jauan Jennings (ankle, rib, shoulder), cornerback Renardo Green (neck), tight end George Kittle (hamstring) and wide receiver Jordan Watkins (calf) again were limited.

The 49ers added wide receiver Marquez Valdes-Scantling (calf) to the injury report as a non-participant.

Bengals edge rusher Trey Hendrickson is officially out of Thursday Night Football. He is among the team's inactives after getting a questionable designation with a hip injury.

He did not play in the second half of Sunday's game and did not practice this week.

Rookie edge rusher Shemar Stewart returns after a four-game absence with an ankle injury, and he will see significant snaps in Hendrickson's stead.

The Bengals have a surprising healthy scratch, with cornerback Cam Taylor-Britt inactive. In the five games he played, Taylor-Britt was on the field for 61 percent of the defensive snaps. He started all 17 games last season.

The Bengals' other inactives are center Matt Lee, wide receiver Jermaine Burton, tight end Tanner Hudson (concussion) and defensive tackle McKinnley Jackson.

The Steelers' inactives are wide receiver Calvin Austin (shoulder), offensive guard Andrus Peat, defensive tackle Logan Lee and defensive end DeMarvin Leal.
