Jones was limited at Thursday's walkthrough due to a back injury.

Jones has been listed with hip, hamstring, chest and rib issues at various points this season, but he has yet to miss a game after averaging 2.7 absences per campaign in his seven seasons with the Packers. In the end, though, his status will be monitored in the coming days to ensure he'll be available Monday against the Bears.

Pollard (ankle) isn't practicing Thursday, Turron Davenport of ESPN.com reports.

Pollard has now sat out both of the Titans' first two Week 15 practices, making his activity (or lack thereof) in Friday's session important with respect to determining his status for Sunday's game against the Bengals. The 27-year-old has suited up in all 13 of the Titans' contest to date, but if Pollard is forced to miss his first game of the season Sunday, Tyjae Spears would likely have a path to double-digit touches out of the backfield.

Homer (head) is listed as a full participant in Thursday's walkthrough practice.

Homer was forced off the field during Sunday's loss to the 49ers due to a head injury, but it appears he's now fully recovered. With D'Andre Swift (groin) and Roschon Johnson (concussion) both listed as non-participants Thursday, Homer's availability as a backfield depth option may be key heading into Monday's divisional road matchup against the Vikings.

Johnson (concussion) was a non-participant at Thursday's walkthrough.

Johnson has been a listed DNP since sustaining a concussion during a Thanksgiving day loss at Detroit, sitting out Week 14 at San Francisco so far. With no activity to speak of yet, he clearly hasn't made much progress through the protocol for head injuries. Meanwhile, fellow RB D'Andre Swift (groin) also was a non-participant Thursday, and Travis Homer (head) was listed as full. Consequently, the state of the Bears backfield remains in flux ahead of Monday's game in Minnesota.

Swift (going) didn't take part in Thursday's walkthrough.

Swift dealt with a quadriceps injury last week but still suited up this past Sunday at San Francisco. He didn't find much success, though, turning 15 touches into 40 yards from scrimmage on a 79 percent snap share. He's now tending to a new health concern, while fellow RB Roschon Johnson (concussion), who was inactive Week 14, also sat out Thursday, and Travis Homer (head) was listed as full. As a result, the Bears backfield will be monitored closely to see who among the trio may be available Monday in Minnesota.

Irving (back/hip) isn't taking part in Thursday's practice, Greg Auman of Fox Sports reports.

Irving will go down as a non-participant for the second straight practice, setting up Friday's session as a critical one in forecasting his odds of playing this Sunday against the Chargers. The rookie began Week 14 in a similar fashion, as he also sat out the Buccaneers' first two practices before returning to the field in a limited capacity Friday. He was listed as questionable prior to suiting up for Sunday's eventual 28-13 win over the Raiders, but he bowed out early after playing just 10 snaps. As a result, Irving might need to put in a full practice Friday for fantasy managers to feel more confident about his health heading into the Buccaneers' Week 15 matchup.

Guerendo (foot) remains listed as questionable for Thursday's game against the Rams but insists he "feels good" and plans to play, sources tell Adam Schefter of ESPN.

After Christian McCaffrey (knee) and Jordan Mason (ankle) were moved to injured reserve last week, Guerendo stepped in as the 49ers' starting running back in this past Sunday's 38-13 win over the Bears. He turned in a big performance, rushing 15 times for 78 yards and two scores while chipping in two catches for 50 yards before exiting late in the contest with a sprained foot. The 49ers listed Guerendo as a non-participant on injury reports released Monday and Tuesday, but after upgrading to limited activity in Wednesday's walk-through session, the rookie looks like he could be tracking toward playing against the Rams. Official word on Guerendo's status will come when the 49ers release their inactive list 90 minutes before Thursday's 8:15 p.m. ET kickoff, but even if he's cleared to play, the 49ers could aim to limit his workload on a short week. Patrick Taylor and Israel Abanikanda are already on the roster as backup options behind Guerendo, and the 49ers could also elevate Ke'Shawn Vaughn from the practice squad to provide another healthy body out of the backfield.

Prentice went without a carry or target while playing 26 of the Saints' 68 snaps on offense in Sunday's 14-11 win over the Giants.

The fullback has suited up for each of the Saints' 13 games to date and has played double-digit snaps in all but one of those contests, but he's operated almost exclusively as a blocker during his time on the field. He has yet to account for any rushing or receiving yardage on the season, though he drew one target apiece in Weeks 2, 8 and 9.

The Bears signed Freeman to their practice squad Wednesday, Courtney Cronin of ESPN.com reports.

Freeman turned some heads as a rookie in 2018 with Denver when he rushed 130 times for 521 yards (4.0 YPC) and five touchdowns while adding another 72 yards on 14 catches through the air. However, he hasn't since topped his yardage or TD total from that season, and he's yet to get into an NFL game this year despite spending time with Cleveland's practice squad earlier in the campaign. Freeman could get elevated quickly by Chicago, though, if Roschon Johnson (concussion) and Travis Homer (head) miss Monday's Week 15 contest against Minnesota.

Irving (back/hip) missed Wednesday's walk-through practice, Brianna Dix of the Buccaneers' official site reports.

Irving exited late in the first half of this past Sunday's win against the Raiders due to a back injury, which head coach Todd Bowles clarified as tightness one day later, per Scott Smith of the Buccaneers' official site. Irving will have two more chances to prove his health before the team potentially makes a ruling on his status for Sunday's contest at the Chargers. Rachaad White would stand to benefit if Irving is available in only a limited capacity or inactive this weekend, while Sean Tucker would bump up a spot in the backfield pecking order for Tampa Bay.
