The Lions signed Firkser to the active roster from the practice squad Wednesday.

Firkser signed with the Lions' practice squad in mid-November and was elevated for their Week 12 win over the Giants. With both Brock Wright (neck) and Sam LaPorta (back) sidelined, Firkser should have a chance to be active for Thursday's game against the Packers.

Adkins (knee) did not practice Wednesday.

Adkins has missed Denver's last three games with the knee issue. He has yet to practice in any capacity since suffering the injury, so there should be significant doubt about his status for Denver's Week 13 matchup against the Commanders.

Sinnott (ankle) doesn't have an injury designation ahead of Washington's matchup versus the Broncos on Sunday.

Sinnott is healthy again after sustaining an ankle injury in the Week 10 loss to Detroit. The 2024 second-round pick should resume his role as the team's No. 3 tight end against Denver.

Njoku (knee) was limited at practice Wednesday.

Njoku continues to manage a knee issue, but as long as he's able to practice fully by Friday he'll be on track to approach Sunday's game against the 49ers without an injury designation. With just one catch (on two targets) over his last two games, a span in which fellow TE Harold Fannin has combined for six catches on 11 targets, Njoku profiles as a hit-or-miss Week 13 fantasy lineup option.

Mayer (ankle) didn't practice Wednesday.

Mayer exited this past Sunday's loss to the Browns after logging 13 snaps on offense, and the tight end's DNP on Wednesday clouds his Week 13 status. Mayer now has two more chances to practice before the Raiders unveil their final injury designations ahead of Sunday's game against the Chargers.

Waller (pectoral) has had his 21-day practice window opened and was a limited participant in Wednesday's session, David Furones of the South Florida Sun Sentinel reports.

Waller is practicing for the first time since suffering a pectoral injury Week 7 versus the Browns and being placed on IR. While it's possible the veteran tight end could gain clearance to retake the field as early as Sunday's contest against the Saints, he may first need to prove an ability to handle full practice reps. Once back in action, Waller will join Jaylen Waddle (foot), Malik Washington and RB De'Von Achane as one of the Dolphins' top options in the passing game. In the event that Waller misses any more time, Greg Dulcich will continue to operate as Miami's top pass-catching tight end.

Okonkwo (foot) was a limited participant in Wednesday's practice, Jim Wyatt of the Titans' official site reports.

Okonkwo has regularly played through his lingering foot injury as of late, so as long as he maintains at least a limited participation level at practice there will be no genuine cause for concern about his availability for Sunday's game against the Jaguars. He logged three limited practices Week 12 but wasn't assigned an injury designation heading into Tennessee's loss to the Seahawks, in which he secured three of four targets for 40 yards.

Long (hip/knee) was a full participant in Wednesday's practice.

Long has missed three straight games while managing a pair of injuries, but he now appears back to full health and ready to retake the field Sunday versus the Titans. He'll handle the No. 2 tight end role behind Brenton Strange, who returned from IR in Week 12 to lead Jacksonville in receiving against Arizona, securing all five of his targets for 93 yards.

Wright (neck) has been ruled out for Thursday's game against the Packers, Colton Pouncy of The Athletic reports.

Wright was held out of all three walkthroughs during Week 13 prep and thus will miss his first game of the season due to a neck injury. With Sam LaPorta (back) on injured reserve and unlikely to play again this season, Ross Dwelley will be the primary beneficiary among Lions tight ends Thursday, while Anthony Firkser and Zach Horton are candidates to be elevated from the practice squad. Wright's next chance for game action is next Thursday, Dec. 4 versus the Cowboys.

Bates (ankle) didn't practice Wednesday, Zac Jackson of The Athletic reports.

Per Jackson, the Kentucky product is likely out for Sunday's contest against the 49ers after sustaining an ankle injury in the Week 12 win over the Raiders. Bates has appeared in seven games for the Texans and Browns this season, failing to record an offensive stat across 70 total snaps (41 on offense, 29 on special teams).
