Packers Place Warren Brinson on Injured Reserve With Groin Injury, Down to 52-Man Roster for Buccaneers Game

GREEN BAY — Warren Brinson's second NFL season is on hold before it ever really started. The Packers placed the second-year defensive lineman on injured reserve Saturday with a groin injury, yet another cruel turn in a year that has refused to let him on the field. Head coach Matt LaFleur said Brinson will miss "a significant amount of time," though he stopped short of declaring the season over. With no corresponding roster move, Green Bay will enter Sunday's Week 4 game against the Tampa Bay Buccaneers with a 52-man roster — and a defensive line rotation that is suddenly thinner than anyone in the building planned for.

The injury itself sounds almost mundane, which is what makes it so frustrating. Brinson slipped in Wednesday's practice, felt the groin, and just like that, a season of buildup evaporated. Under injured reserve rules, he must miss a minimum of four games: the Buccaneers in Week 4, the Bears in Week 6, the Cowboys in Week 7, and the Lions in Week 8. The earliest he could return is Week 9. LaFleur's phrasing — "a significant amount of time" — suggests the team is bracing for the longer end of that absence, even if it hasn't closed the door on a return.

A season that never got started

What stings most about the groin injury is what came before it. Brinson missed the first three games of the season with a calf injury suffered during pregame warmups on Aug. 21, a freak occurrence that cost him the entire opening month. He had come out of training camp considered a potential starter on the interior of the defensive line — a second-year leap candidate the coaching staff was openly excited about. Instead, he has yet to take a single regular-season snap in 2026.

For a young player, that kind of lost time compounds. Defensive line play in the NFL is about rhythm and technique as much as talent; reps are the currency, and Brinson's account is empty. The Packers drafted him 198th overall in the sixth round of the 2025 NFL Draft out of Georgia, where he was part of the Bulldogs' 2022 national championship team, and signed him to a four-year, $4.43 million rookie contract in May 2025. As a rookie he appeared in 11 games, logging 273 defensive snaps with 13 tackles, 3 quarterback hits, and half a sack. Solid rotational production for a sixth-rounder — the kind of foundation a second-year jump is built on. Now that jump is on ice until at least November.

The rotation math gets uncomfortable

Green Bay carried seven interior defensive linemen on its initial 53-man roster: Devonte Wyatt, Javon Hargrave, Karl Brooks, rookie Chris McClellan, Jonathan Ford, Anthony Campbell, and Brinson. On paper, seven deep is a luxury. In practice, the number is already shrinking. Campbell is out for Sunday's game against Tampa Bay with an ankle injury, which means the Packers are effectively down to five healthy interior linemen for Week 4 — and that's before accounting for the 52-man roster forcing tough choices elsewhere.

The absences are not limited to the defensive front, either. Left guard Aaron Banks and offensive lineman Jacob Monk are also out against the Buccaneers. This is the part of the season when depth charts get stress-tested, and Green Bay's is being tested early. The coaching staff now has to manage snap counts carefully: Wyatt and Hargrave are the anchors, Brooks and McClellan the rotation, Ford the depth — and behind them, very little margin for another bad Wednesday.

Third man down

Brinson is the third Packer from the initial 53-man roster to land on injured reserve, and the list reads like a rundown of positions Green Bay could least afford to lose. Right tackle Zach Bako-Bewele is out for the season with a knee injury. Wide receiver Jayden Reed is out for the season with a neck injury. There is some relief on the horizon: wide receiver Savion Williams and edge rusher Collin Oliver are both eligible to return after Week 4. The physically unable to perform list still holds edge rusher Micah Parsons, nose tackle Jordon Riley, and tight end Luke Musgrave. Linebacker Edgerrin Cooper, at least, has cleared concussion protocol.

It is worth pausing on the sheer volume. When a team has multiple starters and key rotational players cycling through IR, PUP, and the injury report in the first month, the season becomes an exercise in survival as much as execution. The Packers' training staff and the front office's roster construction are under the microscope — not necessarily because anyone did anything wrong, but because the margin is gone.

What Sunday looks like

The timing could be worse, in one narrow sense: Tampa Bay comes to Lambeau without quarterback Baker Mayfield, turning instead to rookie Jalon Daniels for the start. A rookie quarterback making a road start is exactly the kind of matchup where a deep, fresh defensive line rotation feasts — waves of pass rushers, no drop-off, constant pressure. The Packers will have to generate that pressure with a thinner wave than they drew up in August.

For Brinson personally, the road back is now a rehab schedule and a waiting game. Groin injuries are notoriously tricky — easy to re-aggravate, punishing to rush — which likely explains LaFleur's cautious tone. The best-case scenario is a Week 9 return with half a season left to salvage the year. The worst case is the one nobody at 1265 Lombardi Avenue wants to say out loud.

The bigger picture

Step back and the Brinson story is a reminder of how fragile NFL roster-building really is. A sixth-round pick out of Georgia grinds through a solid rookie year, earns first-team consideration in camp, signs a team-friendly four-year deal — and then a calf in warmups and a slip in practice wipe out two months. No single decision caused it. No one is to blame. It is just the physics of a violent sport played by large men changing direction at full speed.

What matters now is how Green Bay adapts. The Packers chose not to make a corresponding roster move, signaling they believe the current group — even at 52 men, even down two interior linemen on Sunday — can hold the line until reinforcements arrive. Williams and Oliver become eligible after Week 4. The calendar says Brinson can return in Week 9. Between now and then, it's Wyatt, Hargrave, and the rest of the room, playing more snaps than anyone planned, against quarterbacks who will test exactly that kind of attrition.
