49ers Give Brock Purdy A Meaningful Preseason Test After Rough Practice

The San Francisco 49ers aim to sharpen their starting lineup, including Brock Purdy's preseason return, against the Chargers in a critical test ahead of the regular season.

Brock Purdy is set to get his first preseason run of 2026, and the 49ers are bringing a much larger chunk of their front-line group along with him Thursday night against the Chargers.

After mostly parking their starters in last week’s exhibition opener against Tennessee, Kyle Shanahan is taking a different approach in Preseason Week 2. San Francisco is coming out of a joint practice that didn’t go smoothly on offense, and Shanahan wants his top group to sharpen its timing in live game action.

That means Purdy should be under center for a brief but meaningful stint. The expectation is that he’ll work somewhere between one and two series as the 49ers try to clean up execution before the regular season begins.

The offensive picture still comes with a few notable absences. Christian McCaffrey remains out with minor lower body tightness, while Mike Evans is dealing with minor quad tightness and Christian Kirk is nursing a calf strain. With those pieces limited, early receiver work figures to center on Deebo Samuel and Demarcus Robinson.

There’s also a key look coming on the interior offensive line. Rookie guard Dominick Puni is working his way back from a concussion, and the staff will be watching that battle closely when the starters are on the field.

On defense, Raheem Morris has reasons to pay close attention after the unit had a rough stretch against Justin Herbert in joint practices. Fred Warner is expected to anchor the group for an early series, but the pass rush will have a different feel with Nick Bosa easing back from knee tendinitis. That opens the door for Keion White, Ogbo Okoronkwo, and rookie Gracen Halton to get more of the spotlight along the front four.

The secondary will be under the microscope too. Renardo Green, Ji'Ayir Brown, and Nate Hobbs are among the young defensive backs expected to face a good test against Los Angeles’ starting receivers.

Shanahan made clear the starters won’t be out there long. Their workload is expected to be limited to a single opening drive or, at most, a quarter. After Purdy and the first unit come off the field, Mac Jones is slated to take over at quarterback, giving the 49ers a longer look at players fighting for roster spots and depth jobs.

49ers Camp Suddenly Has A Mac Jones Question Fans Didn't Expect

Kurtis Rourke turned heads in his 49ers debut, and it did more than just add another name to the quarterback mix. Around a camp that already has Brock Purdy working through joint practices with the Chargers and rookie running back Kaelon Black flashing, Rourkes first showing gave the roster a little more intrigue than the team probably expected this early in August.

It also has quietly changed the conversation around Mac Jones, whose contract situation is now part of the backdrop as the preseason unfolds. The 49ers are still juggling routine camp decisions, including Christian McCaffrey being held out of some work as a precaution and bringing back defensive tackle Evan Anderson for depth, but the most interesting question may be whether the quarterback picture is stable enough to last beyond the summer.

49ers Veteran Suddenly Has A Real Week 1 Opening

Sam Okuayinonu has spent the early part of his 49ers career looking like a depth piece with room to grow, but this season could finally give him a clearer path. Entering his third year in San Francisco, he is expected to see more playing time, and the roster picture around him has shifted just enough to make that feel real heading into the opener.

The opening may have arrived sooner than the 49ers planned. With the team still managing injuries along the edge, Okuayinonu could be in line to start or at least handle a meaningful workload right away, giving him a chance to turn a longer look into something more permanent if the early-season rotation stays thin.

49ers Wide Receiver Battle Just Claimed An Unexpected Draft Pick

The 49ers wide receiver competition took an early turn before their first preseason game, with Junior Bergen waived after a camp that had highlighted his return ability. Bergen had been viewed as a long shot to crack San Franciscos roster, and the teams depth at receiver made every fringe spot difficult to hold onto as roster decisions started to come due.

Bergen did not stay on the wire long. The Jets claimed him and made room by moving on from an undrafted free agent, a quick reminder that even players on the edge of the 49ers roster can still draw interest elsewhere. For San Francisco, it is another small but notable cut in a crowded position battle that could keep shifting as preseason unfolds. [Read more 🡒]
