Here are Wednesday’s practice squad transactions:

Arizona Cardinals

Buffalo Bills

Cleveland Browns

Jacksonville Jaguars

Kansas City Chiefs

Los Angeles Chargers

Philadelphia Eagles

San Francisco 49ers

  • Signed: T Isaac Alarcón

Seattle Seahawks

Both Jacksonville and San Francisco had their practice squads filled up with 16 players apiece, but Zierer and Alarcón were both able to be added as players in the league’s International Player Pathway Program. Zierer is a German-born lineman, and Alarcón was born in Mexico.

Dolphins Place CB Cornell Armstrong On IR

The Dolphins’ banged-up secondary took another hit Wednesday. The team placed nickel cornerback Cornell Armstrong on injured reserve. He’ll miss at least four games after suffering a hamstring injury in a loss to the Panthers last Sunday.

The Dolphins now have three nickel corners on IR. Along with Armstrong, Jason Marshall and Artie Burns are on the shelf. Marshall has missed two games with a hamstring injury, which opened up playing time for Armstrong, while Burns won’t factor in at all this season after tearing his ACL during training camp.

The injury woes at nickel CB are only part of the problem in Miami’s secondary. Like Burns, corner Kader Kohou tore his ACL in July. The Dolphins have also gone without corner Storm Duck since he injured his ankle in a Week 1 loss to the Colts. Their absences help explain why Miami’s defense ranks last in the NFL in opposing passer rating and completion percentage,

Armstrong first became a Dolphin when they chose him in the sixth round of the 2018 draft. He played in 15 games as a rookie, but the Dolphins released him after the season. Armstrong went on to see action with the Texans (2019) and Falcons (2022) before Miami brought him back over the summer when it placed Burns on IR. The 30-year-old has played in three games this year and registered two tackles.

Having lost another nickel CB, safety Minkah Fitzpatrick will have to continue helping the Dolphins fill that role, per Barry Jackson of the Miami Herald. With Fitzpatrick needed elsewhere, the Dolphins signed practice squad safety Jordan Colbert to their active roster on Wednesday. The 25-year-old made his NFL debut in the Dolphins’ Week 3 loss to the Bills. All 12 of his snaps came on special teams.

To take Colbert’s spot on their practice squad, the Dolphins signed Kendall Sheffield. The former Falcon, 49er, Titan, and Jet has appeared in 49 games (20 starts) since debuting in 2019. Sheffield signed with the Dolphins in late May, but they cut him in late August. They elected to bring him back after working out free agent corners Ethan Robinson, Daequan Hardy, and Myles Purchase on Tuesday, according to Jackson.

Following the 53-man roster cutdown deadline Tuesday, many teams will make slight tweaks to their rosters. In addition to waiver claims, teams can begin constructing their 16-man practice squads today. These BroncosChargersChiefs and Raiders moves are noted below.

Chargers Place LB Junior Colson On IR; Taylor Heinicke Among Team’s Cuts

The Chargers placed a key defender on season-ending IR and made a quarterback decision. Here are the Bolts’ moves to reach the 53-man roster limit:

Released:

Waived:

Waived/injured:

Placed on IR:

Placed on IR (return designation):

It is not known what injury Colson suffered — teams do not have to disclose injuries until Week 1 — but this is a significant setback for the former Jim Harbaugh Michigan pupil. Colson entered training camp with a chance to earn the starting linebacker job alongside Daiyan Henley; instead, he will miss the season. Harris and Leonard will be eligible to return from IR after four games; their IR-return placements drop the Bolts’ injury activation count from eight to six.

It is possible the Chargers circle back to Heinicke, who is a vested veteran. A practice squad stashing could make sense, but Trey Lance is also a vested veteran now. The Bolts are keeping the former No. 3 overall pick on their 53-man roster, while Heinicke’s status is uncertain. The Chargers re-signed Heinicke to a one-year, $2.5MM deal. They are positioned to eat $2MM in dead money due to the guarantees given to their 2024 backup.

Chargers Announce 18 UDFA Signings

After adding nine players throughout this weekend’s draft, the Chargers still had plenty of room for rookie additions. Los Angeles announced their 18-man undrafted free agent signing class shortly after the event closed, disclosing these players as signees:

After slightly favoring offense (five players to four on defense) during the draft, Los Angeles evens things out by favoring the defense (10:8) in the undrafted class, giving them 13 offensive rookies and 14 defensive rookies in 2025.

Once heralded as the quarterback of the future set to take over the Clemson program after Trevor Lawrence, Uiagalelei ends up in Los Angeles after stops with Oregon State and the Seminoles. Sanders was expected to be a late-Day 3 selection. Sanders rushed for 1,443 yards and 10 touchdowns in 2022 for Arkansas before injuries limited him in 2023. He transferred to South Carolina and tallied 881 yards and 11 scores on the ground, adding 316 yards and 2 touchdowns through the air.

The team loaded up on flyers in the secondary this year. After drafting safeties with each of their last two picks, the Chargers added one more in free agency and signed four undrafted cornerbacks. Reed is maybe the most capable of the group. One of Deion Sanders‘ cast-outs at Colorado, Reed transferred to Oregon for two strong years, collecting 26 passes defensed and five interceptions in his four years of college. Per Aaron Wilson of KPRC 2, Reed’s UDFA contract includes $100K of base salary guaranteed plus a $15K signing bonus.
