Jones (knee) is listed as questionable for Sunday's contest versus the Jaguars, Nick Wagoner of ESPN.com reports.

Jones emerged from a second consecutive start in place of Brock Purdy (left shoulder/toe) this past Sunday against the Cardinals with a sprained PCL in his left knee. It limited Jones in practice Wednesday and Thursday, and his status now is up in the air ahead of Week 4 action. Coach Kyle Shanahan already told Wagoner that Purdy will start this weekend, so Jones will be the No. 2 QB, assuming he's active.

Pearsall (knee) is listed as questionable for Sunday's contest against the Jaguars, Nick Wagoner of ESPN.com reports.

Pearsall didn't practice Wednesday due to a knee injury but was able to do so in a limited capacity one day later. Before that first session, he told Jennifer Lee Chan of NBC Sports Bay Area that he'd play if there was a game that day, but the 49ers seemingly are less optimistic about the second-year wide receiver's status for Week 4. In the end, Pearsall's availability will be confirmed, one way or another, about 90 minutes before Sunday's 4:05 p.m. ET kickoff.

Walker (quadriceps) was a full participant at practice Friday, Aaron Nagler of Cheesehead TV reports.

Walker was limited at the team's first two practices of the week due to a quadriceps injury, but he won't carry an injury designation into the weekend. The 25-year-old will start in his regular spot at left tackle against Dallas on Sunday Night Football.

Banks (groin) is doubtful to play in Sunday night's contest against the Cowboys, Aaron Nagler of Cheesehead TV reports.

Banks did not participate at any of the team's three practices throughout the week due to an apparent groin injury. If he can't go in Week 4, Jordan Morgan and Sean Rhyan would be candidates to start at left guard in his place against Dallas.

Jennings (shoulder/ankle) is listed as questionable for Sunday's game versus the Jaguars, Nick Wagoner of ESPN.com reports.

Jennings was listed as a non-participant on five straight injury reports due to shoulder and ankle injuries before getting back on the field Friday, giving him a chance to return to action this weekend. His status will be confirmed, one way or another, about 90 minutes before Sunday's 4:05 p.m. ET kickoff, but if he's able to suit up, he'll be on the receiving end of passes from No. 1 QB Brock Purdy (left shoulder/toe), who has been cleared for his first game action since Week 1.

Tom (oblique) has been ruled out for Sunday night's contest in Dallas, Aaron Nagler of Cheesehead TV reports.

Tom will be unavailable for Week 4 while he nurses an oblique injury, which sidelined him at practice for the entirety of the week. Jordan Morgan is a top candidate to take over at right tackle against the Cowboys.

Purdy (left shoulder/toe) doesn't have a designation for and will start Sunday's game against the Jaguars, Nick Wagoner of ESPN.com reports.

Purdy hasn't played since Week 1 due to a turf toe variant and an AC joint sprain in his left shoulder, but he'll officially retake the reins of the 49ers offense from backup Mac Jones (knee). In his return to the lineup, Purdy will be taking on a Jacksonville pass defense that has allowed 209.3 yards per game (17th in the NFL).

Mayer (concussion) has been ruled out for Sunday's game against the Bears, Paul Gutierrez of Raiders.com reports.

Mayer didn't practice this week, so his next chance to see game action will arrive Sunday, Oct. 5 against the Colts. In Mayer's absence, fellow TE Ian Thomas is in line to serve as Brock Bowers' top backup Sunday, with Albert Okwuegbunam and Carter Runyon representing possible Week 4 practice-squad elevations.

Smith (heel) was a full participant at practice Friday.

Smith was limited at practice Thursday due to a heel injury before upping his participation Friday. He won't carry an injury designation into the weekend, and Smith will be in his starting role at right tackle versus the Rams on Sunday.

Winston (hamstring) is questionable to play Sunday in Houston.

Winston was a limited participant at practice for all three of the team's sessions this week, but he'll ultimately be forced to miss a fourth game in a row with a hamstring injury. In his absence, Quandre Diggs will continue to see an increase in workload against the Texans.
