Pollard (ankle/illness) has been ruled out for Sunday's game against the Jaguars, Jim Wyatt of the Titans' official site reports.

Pollard was previously listed as questionable for the contest with an ankle injury, but with the running back now also dealing with an illness, he's been downgraded to out by the Titans. With Pollard unavailable, Tyjae Spears is slated to lead the team's Week 17 backfield, with Julius Chestnut and Joshua Kelley on hand to mix in.

The Panthers signed Boone to their active roster Saturday ahead of Sunday's game against the Buccaneers, Darin Gantt of the Panthers' official site reports.

With fellow running back Chuba Hubbard (calf) having landed on injured reserve, Boone will be needed for the Panthers' final two regular-season games. Per Gantt, Boone and Raheem Blackshear are in line handle backfield duties in Hubbard's absence, a context that makes Boone worth a roster dart for those scrambling for Week 17 running back help.

Pollard, who was previously listed as questionable for Sunday's game against the Jaguars with an ankle injury, is also dealing with the flu, Jeremy Fowler of ESPN.com reports.

Per Fowler, Pollard -- who had planned to play through his ankle issue -- isn't expected to travel with the Titans on Saturday. If he's deemed unable to play Sunday, Tyjae Spears would be in line to see an expanded role in the team's Week 17 backfield.

Gibson will start at running back over Rhamondre Stevenson in Saturday's game against the Chargers, Evan Lazar of the Patriots' official site reports.

On the heels of his recent fumbling issues, Stevenson is slated to give way to Gibson on Saturday, at least in terms of the starting assignment. That said, we'd still expect Stevenson to see his share of work versus the Chargers, but his ball security issues of late should lead to Gibson seeing a higher percentage of New England's backfield snaps than usual in Week 17.

Stevenson won't start at running back for the Patriots in Saturday's game against the Chargers, Ian Rapoport of NFL Network reports.

In the wake of his recent fumbling issues, Stevenson is slated to give way to fellow RB Antonio Gibson, at least in terms of Saturday's start. That said, we'd still expect Stevenson to see his share of work versus the Chargers, but his ball security issues of late could lead to Gibson logging a higher percentage of New England's backfield snaps compared to his usual in Week 17.

Dobbins (knee) is listed as active for Saturday's game against the Patriots, Eric Smith of the Chargers' official site reports.

The return of Dobbins -- who was activated from IR on Friday after having missed four games since the Chargers' Week 12 loss to the Ravens -- arrives at an opportune juncture, with fellow running back Gus Edwards having been ruled out with an ankle issue. Prior to sustaining his knee injury, Dobbins recorded 766 yards and eight touchdowns on 158 carries (4.8 yards per carry) and added 28 catches for 134 yards in 11 contests. In his return to the lineup, the 26-year-old will have an opportunity to reclaim the lead role in a Week 17 Los Angeles backfield that will also include Kimani Vidal and Hassan Haskins. The 9-6 Chargers can clinch a playoff spot with a win Saturday.

Hubbard (calf/knee) has been placed on IR by the Panthers, Darin Gantt of the team's official site reports.

Hubbard, who was limited at practice Friday, was initially listed as questionable for Sunday's game against the Buccaneers. However, after practice Hubbard noted that he was dealing with some pain, and an MRI Friday night revealed a Grade 2 calf strain. With Hubbard sidelined for Carolina's final two games, Raheem Blackshear, as well as practice squad members Mike Boone and Emani Bailey, are next up for the team's backfield work. Per Adam Schefter of ESPN, Blackshear and Boone (pending his elevation) are likely to share RB duties versus Tampa Bay.

With Chuba Hubbard (calf/knee) on track to be placed on IR ahead of Sunday's game against the Buccaneers, Boone is a candidate to share backfield work with Raheem Blackshear, according to Adam Schefter of ESPN.

Apart from Hubbard, Blackshear is currently the only other running back on the Panthers' 53-man roster, but Boone and Emani Bailey are on the team's practice squad, and are thus candidates for elevation ahead of Week 17 action. Per Schefter, Blackshear and Boone appear likely to share backfield work versus Tampa Bay, a context that makes Boone a potential lineup dart for those in need of RB help down the stretch.

Blackshear is expected to see added work during the Panthers' final two regular season games with Chuba Hubbard (calf/knee) set to be placed on injured reserve Saturday, David Newton of ESPN.com reports.

Blackshear is currently the only other running back on the Panthers' 53-man roster ahead of Sunday's game against the Buccaneers, but Mike Boone and Emani Bailey are on the team's practice squad. Blackshear and Boone will most likely to share backfield work in Week 17, though to what extent is unclear.

The Panthers are expected to place Hubbard -- who is listed as questionable for Sunday's game against the Buccaneers -- on injured reserve due to a calf and knee injury, Adam Schefter of ESPN and NFL Network's Tom Pelissero report.

Per Pelissero, the injury that is slated to lead to the anticipated roster move is not considered major, but the 4-11 Panthers, who are not in playoff contention, don't want to make it worse. In Hubbard's looming absence for the team's final two games, Raheem Blackshear is on track to see an expanded role, with Mike Boone and Emani Bailey candidates to be elevated from Carolina's practice squad.
