Flacco (right shoulder) was limited at practice Thursday, Paul Dehner Jr. of The Athletic reports.

Flacco also was limited Wednesday, but at this stage there's no reason to think he'll be unavailable Sunday against the Patriots. However, with Joe Burrow (toe) having logged his second straight full practice, while taking snaps with the first-team offense in the process, per Adam Schefter of ESPN, it's uncertain if Flacco will continue as the Bengals' starting QB this weekend, with that assignment (or lack thereof) hinging on whether Burrow is deemed fit for his first game action since Week 2.

Burrow (toe) was a full participant in Thursday's practice.

While Burrow's ability to practice without any restrictions for the second day in a row was noteworthy enough in itself, perhaps the more important takeaway from Thursday's session was that he took all of his reps with first-team offense in the portion that was open to the media, per Ben Baby of ESPN.com. Meanwhile, Joe Flacco (shoulder) -- who had started each of the past five games -- was listed as a limited participant and worked behind Burrow during individual drills, ostensibly as the Bengals' No. 2 quarterback. Prior to practice, head coach Zac Taylor was non-committal about the franchise signal-caller being activated from injured reserve for Week 12, but Burrow certainly would appear to have a strong chance at returning to the lineup this Sunday against New England. The Bengals will wait and see how Burrow's surgically repaired left big toe responds to a third straight day of practice Friday before providing an update on his status heading into the weekend.

Jones was limited at practice Thursday due to a calf injury.

Jones wasn't on the Colts' initial Week 12 injury report, so his addition to it Thursday is of note. That said, Stephen Holder of ESPN.com indicated that at this stage he's not sensing any reason for alarm regarding Jones. Nonetheless, what the QB is able to do at practice Friday and, in turn, what (if any) injury designation he carries ahead of Sunday's game against the Chiefs is now worth monitoring.

Dart (concussion) remained a limited non-contact participant at Thursday's practice, Dan Salomone of the Giants' official site reports.

Interim head coach Mike Kafka told Pat Leonard of the New York Daily News earlier Thursday that there was a chance Dart would gain clearance from the concussion protocol after the Giants' second Week 12 practice, but that didn't come to pass. Instead, Dart maintained his activity level from Wednesday, giving him just one more chance this week to get back to full. In the end, he'll need to be cleared by an independent neurologist in order to play Sunday at Detroit, but if Dart is unable to, Jameis Winston is the next QB up on the depth chart.

Rodgers (left wrist) was limited in his return to practice Thursday, Brooke Pryor of ESPN.com reports.

After logging a DNP on Wednesday, Rodgers returned to a limited session a day later, while sporting "some sort of stabilizer" on his left non-throwing wrist, per Pryor. As for his chances of playing Sunday against the Bears, Rodgers told Pryor on Wednesday that he'd need to be able to "protect" himself in order to do so. In any case, unless Rodgers practices fully Friday, he'll presumably head into the weekend with an injury designation. If he's unavailable versus Chicago, Mason Rudolph would be in line to start in his place.

Rodgers (wrist) was present for practice Thursday, Brooke Pryor of ESPN.com reports.

Per Pryor, Rodgers' left wrist was in "some sort of stabilizer" as he was spotted doing individual reps Thursday. On the heels of a DNP on Wednesday, the veteran QB's presence at practice a day later is encouraging, though it seems likely he'll be officially listed by the Steelers as a limited participant.

Gabriel (concussion) is not practicing Thursday, Scott Petrak of the Elyria Chronicle-Telegram reports.

Browns coach Kevin Stefanski has already unannounced that Gabriel will not start Sunday versus the Raiders even if available, but by all accounts the rookie third-round pick seems on track to sit out Week 12 while in the concussion protocol. Meanwhile, Shedeur Sanders will start versus Las Vegas. Gabriel will have one more chance to log practice reps Friday, but in the likely even that he's ruled out, Bailey Zappe will figure to be elevated from the practice squad to handle No. 2 reps behind Sanders.

Jackson (ankle) is participating in Thursday's practice, Jeff Zrebiec of The Athletic reports.

Jackson is back on the practice field in at least a limited capacity after having missed Wednesday's session due to an ankle issue. He previously began Week 11 prep as a non-participant due to knee soreness but then managed to log two consecutive full practices and suit up for Baltimore's win over the Browns. The Ravens' official Thursday injury report will reveal whether Jackson is on a similar upward trajectory for Sunday's matchup against the Jets.

Bengals head coach Zac Taylor was unwilling to make a firm commitment Thursday when asked whether Burrow (toe) will play Sunday versus the Patriots, Ian Rapoport of NFL Network reports. "I'm not there yet," Taylor said.

Burrow was listed as a full participant at practice Wednesday and took part in 11-on-11 drills. Rapoport relays that Burrow's activity level Thursday will be crucial in determining his availability for Sunday. If Burrow is able to log two straight full sessions without any soreness or setbacks, it will be a strong sign that the star quarterback's recovery from Sept. 19 surgery to address a Grade 3 sprain of the big toe on his left foot has gone smoothly enough for him to return to game action. Cincinnati's coaching staff has explicitly refrained from ruling Burrow out for Sunday, but it sounds as though more information on his chances of returning may not arrive until after the team's final practice of the week Friday.

Mayfield was limited at Wednesday's walkthrough due to an illness.

An illness has swept the Buccaneers' roster at the start of Week 12 prep, with all of Mayfield, WR Emeka Egbuka, O-linemen Luke Goedeke, Graham Barton and Dan Feeney and D-lineman Logan Hall operating with a cap on their reps. Mayfield will have two more chances to get back to full participation this week, with Friday's injury report ultimately revealing whether or not he has a designation for Sunday's game at the Rams.
