NFL Practice Squad Updates: 8/31/25

Here are Sunday’s only practice squad transactions to close out the final weekend of 2025 without NFL football:

Los Angeles Chargers

Philadelphia Eagles

The Chargers brought two undrafted rookies onto their practice squad, making space by letting go of Barnhart and putting the veteran, Reagor, on the injured list. Barnhart started three positions on the Wolverines offensive line during Michigan’s championship season but went undrafted and failed to appear in an NFL game as a rookie last year.

Johnson rushed for over 1,200 yards and 14 touchdowns in his final year at South Dakota State. Grimm was the top receiver at Kansas last year after averaging 623 receiving yards and six touchdowns over his last three seasons for the Jayhawks.

Wednesday NFL Transactions: AFC West

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.

NFL Reserve/Futures Contracts: 1/13/25

Many teams have started signing players to reserve/futures contracts, allowing the organization to retain (routinely) young, practice squad players through the offseason. Here are the latest reserve/futures contracts:

Arizona Cardinals

Cleveland Browns

  • DT Ralph Holley

Denver Broncos

Green Bay Packers

Los Angeles Chargers

Pittsburgh Steelers

  • OT Doug Nester

Chargers Waive RB Isaiah Spiller, T Alex Leatherwood; Get Down To 53

The Chargers made their way down to 53 players today with a number of waives and releases:

Released:

Waived:

Placed on IR:

  • OLB Chris Collins
  • T Tyler McLellan
  • OLB Chris Rumph
  • IOL Bucky Williams

Placed on IR (designated for return):

There aren’t too many surprises here. Of the veterans, Parham fell victim to the addition of two veteran receiving options, and Quarterman was a long-time special teamer.

Michigan wide receiver Johnson was the only drafted rookie who failed to make the roster after being selected in the seventh round. While no undrafted rookies made the roster either, McLellan and Williams will stick around on the IR, where they will remain out for the year. Niemann will have the option to be activated after four games.

The biggest cuts we otherwise see are Spiller, who got some run as a depth option at running back last year, and Leatherwood. Leatherwood, the former first-round pick out of Alabama, continues to struggle to find his place in the NFL.

Chargers Agree To Terms With 21 UDFAs

The Chargers’ roster is set to look very different in 2024. With the departure of key players such as Austin Ekeler, Keenan Allen, Mike Williams, Gerald Everett, Kenneth Murray, Austin Johnson, and several others, Los Angeles had plenty of room on the roster for this summer, even after selecting a nine-man class in the 2024 NFL Draft. To fill out the roster, the Chargers turned to these undrafted free agents:

Barnhart brings an intriguing versatility to a new Chargers offense led by offensive coordinator Greg Roman. Roman loves a guy who can play all over the line (see Patrick Mekari in Baltimore), and Barnhart started games at every offensive line spot but center during his time with the national champion Wolverines. In the team’s championship-winning season alone, Barnhart started eight games at right tackle, four games at left tackle, and three games at right guard en route to second-team All-Big Ten honors.

Heins is another great fit for a Roman offense. Helping the Jackrabbits to back-to-back FCS national championships, Heins established himself as a starter due to his in-line blocking abilities. While, in his three years as a full-time starter, he only racked up 989 receiving yards, he also tallied 17 touchdowns in that same stretch.

The team adds two intriguing options at safety, as well. Harper started for the Fighting Irish as a transfer after four years at Oklahoma State. He didn’t make may plays on balls in the air but showed versatility as a nickel option and a blitzer. Dent, a one-time five-star recruit as a junior in high school, has tons of athleticism, he’s just never been able to convert it into on-field production.
