The Chargers’ 53-man roster remains unsettled with two preseason games left, and the unresolved battles at offensive line, wide receiver, and edge rusher will dictate whether this team reaches January. The joint practices and Week 2 exhibition against the San Francisco 49ers serve as the final live-fire evaluation before cuts on August 27.
Here is the breakdown of the three hidden competitions, the one looming quarterback question, and a projection of the final squad.
Battle No. 1: Offensive Line — The Justin Herbert Protection Problem
The left guard spot is open. Jamaree Salyer and Zion Johnson split first-team reps this week. Johnson, a 2022 first-round pick, has struggled with consistency. Salyer offers more power in the run game but loses on quick-twitch pass rushers. Neither has seized the job.
Right tackle is equally murky. Trey Pipkins III surrendered four sacks last season, per Pro Football Focus. The rookie fourth-round pick, Andrew Coker, has flashed in camp but is raw. Center remains the only stable position, anchored by Corey Linsley’s veteran presence.
The 49ers’ defensive front, featuring Nick Bosa and Javon Hargrave, represents the sharpest stress test yet. Herbert was sacked 42 times in 2025. The scheme matters: If the Chargers lean into quick, short-range passes, the winner is the more agile player. If they want deep drops, power wins.
Expect Salyer to start at left guard by Week 1. Coker needs another year.
Battle No. 2: Wide Receiver 3 — The Search for a Field-Stretcher
Keenan Allen and Mike Williams hold the top two spots. The third receiver job is a three-man race.
Quentin Johnston, the 2023 first-round pick, has the vertical speed but drops passes at an alarming rate. His catch percentage last season was 58.7%. Joshua Palmer runs sharper routes and is trusted by Herbert on third down, but he lacks top-end gear. Derius Davis, the sleeper, has elite return ability and has shown improved route discipline in camp.
The red zone data is telling. The Chargers converted only 54.3% of red zone trips into touchdowns in 2025, ranking 19th. A reliable third receiver who can win one-on-one inside the 20 is essential.
Yahoo Sports reported that the 49ers are likely to cut a veteran receiver before Week 1. The Chargers should monitor that waiver wire.
Johnston wins the job on potential. But his margin for error is zero.
Battle No. 3: Edge Rusher — The Khalil Mack Complement
Khalil Mack is the starter. The question is who lines up opposite him, and how much rotation occurs.
Joey Bosa remains on the roster but has missed 14 games over the past two seasons. His health is the single biggest variable on defense. Tuli Tuipulotu, the 2023 second-round pick, recorded 7.5 sacks as a rookie and has added 10 pounds of muscle this offseason. He is the future.
The rotation math is simple: Mack played 82% of defensive snaps in 2025. That number must drop to preserve him for January.
The 49ers’ offensive tackles, Trent Williams and Colton McKivitz, are a brutal test. If Tuipulotu wins consistent pressure against Williams, he forces the coaching staff’s hand.
Recent Super Bowl winners all had two reliable edge rushers. The Eagles had Haason Reddick and Josh Sweat. The Chiefs had Chris Jones and Frank Clark. The Chargers cannot rely on a 34-year-old Mack and a fragile Bosa.
Tuipulotu should start opposite Mack by October. Bosa becomes the rotational piece.
The One Question: Backup Quarterback Risk
Easton Stick is the current No. 2. He has thrown 87 career passes. The coaching staff has shown no public confidence in him beyond standard platitudes.
The 49ers, conversely, carry a proven veteran backup in Sam Darnold. That contrast is stark. If Herbert misses any time, the Chargers’ season collapses.
The team should carry a third quarterback on the 53-man roster. Max Duggan, the 2025 seventh-round pick, has shown mobility in camp but is raw. A trade for a veteran like Gardner Minshew remains the logical move before Week 1.
Do not trust the depth chart here. The risk is too high.
Roster Projection: 53-Man Squad After Week 2
The following projection reflects the depth chart battles above and the likely cuts after the 49ers game.
| Position | Starter | Backup | Cut Watch |
|---|---|---|---|
| QB | Justin Herbert | Easton Stick | Max Duggan |
| RB | Austin Ekeler | Isaiah Spiller | Elijah Dotson |
| WR | Allen, Williams | Johnston, Palmer | Davis, Jalen Guyton |
| OL | Salyer, Linsley, Pipkins | Johnson, Coker | Jordan McFadden |
| EDGE | Mack, Tuipulotu | Bosa, Chris Rumph II | Caleb Johnson |
| CB | J.C. Jackson, Asante Samuel Jr. | Ja’Sir Taylor | Deane Leonard |
The undrafted free agent most likely to earn a spot is safety A.J. Finley, who has impressed on special teams. The 49ers’ roster projection article similarly highlighted two undrafted players making the squad, proving that special teams value often overrides positional need.
The toughest cut will be at receiver. Davis’s return ability gives him the edge over Guyton.
The Playoff Formula
The winners of these three battles determine the season’s trajectory. Salyer at guard stabilizes the pocket. Johnston at receiver stretches the field. Tuipulotu at edge creates a pass rush that can close out fourth-quarter leads.
If the expected winners emerge, the Chargers secure a wild-card spot. Their schedule includes four games against playoff teams from 2025, but the roster is deep enough.
If Bosa regresses or Johnston fails to catch consistently, this team misses the postseason. The margin is that thin.
The 49ers game provides the final evidence. The decisions made after it will define the season.
