General manager John Lynch gave updates on Brandon Aiyuk and Jauan Jennings’ injury timelines on KNBR. He said he doesn’t expect Aiyuk for Week 1 while Jennings has “no timetable” to return for the matchup with Seattle.

Before today’s joint practice with the Denver Broncos, the San Francisco 49ers announced the signing of defensive lineman Michael Dwumfour and the release of cornerback Eli Apple. The team got a boost in practice with the return of DE Nick Bosa and FB Kyle Juszczyk. Former 49ers LB Dre Greenlaw did not practice. S Ji’Ayir Brown did not return to practice.

Let’s get...

The point of having joint practices is to go against somebody in a different colored jersey after a couple of weeks of training camp. It’s a breath of fresh air to gauge the players against another opponent and scheme. However, the main objective is to get out of these sessions injury-free.

Unfortunately for the San Francisco 49ers, that was not the case on Thursday afternoon. First-round pick and the player the Niners are invested in heavily for the next potential decade limped off the field after going down with an injury during a red zone drill. Williams was spotted grabbing...

San Francisco 49ers general manager John Lynch said the team has a theory, thanks to sports science, about “building a mountain that gets you calloused and ready to play football.” Sure, the Niners could do walkthroughs all the way up to Week 1 to ensure everybody was healthy, but this is also a team that intends to play a bunch of young players, and the only way for those players to improve is by playing football.

Lynch said competition is the primary way to get better, so the 49ers have been trying to balance how to get better while making...

The San Francisco 49ers worked out four different defensive tackles Wednesday afternoon. Ahead of Thursday’s joint practice against the Denver Broncos, the team signed one of them. Michael Dwumfour gets another stint with the Niners. To make room, the team released cornerback Eli Apple, who signed on July 28.

Releasing Apple might be a good sign that Renardo Green is close to a return. Head coach Kyle Shanahan was hopeful that Green would return during Week 2 of the preseason against the Las Vegas Raiders, which is next Monday.

Dwumfour signed with the New York Jets under Robert Saleh as...

San Francisco 49ers general manager John Lynch joined KNBR on Thursday morning ahead of the team’s joint practice with the Denver Broncos.

With all of the roster turnover, Lynch said the Niners are still figuring out who they are. The Niners are expecting several new starters on defense. More than likely, multiple rookies. Lynch was asked to rank the 2025 rookie class in order of who stood out the most:

I’m gonna cheat and probably say two guys who have consistently been good. Mykel Williams, because he’s a really good football player. We didn’t feel like there was a...

The San Francisco 49ers are just two days away from their first preseason game, as they’ll host the Denver Broncos on Saturday at Levi’s Stadium at 5:30 p.m.

Before that, they’ll have a single joint practice session against the Broncos, which are usually the sessions with the most fireworks.

Traditionally, the 49ers haven’t played their starters much in the preseason. But, in 2025, they have a younger team with some first and second-year starters, so it could be more beneficial to get game reps ahead of the season.

What is the plan for Saturday against the Broncos?

“I’d be surprised...

The San Francisco 49ers are nearing their first preseason game, as they’ll take on the Denver Broncos on Saturday at Levi’s Stadium to kick off the next phase of the offseason.

It’s been a different year at training camp, as younger faces have gotten more opportunity, be it due to injury or the roster outlook of a certain position group. That has led to more competition all around.

One group filled with young talent is the wide receiver position, where there seems to be a wide-open race for playing time, especially with top wideout Jauan Jennings currently nursing a calf...

Has 49ers rookie Upton Stout put himself in position to start in Week 1? (paywall)
“It wasn’t that long ago when the 23-year-old Stout played as Warner in the “Madden NFL” video game. The fact they communicate with each other on a play-by-play basis has been surreal for Stout, who can be almost too critical of himself at times. He said he just doesn’t want to be a letdown for his teammates, Warner especially.

In his latest KNBR radio appearance, Warner didn’t sound too disappointed: “Right now the guy that’s sticking out to me most, I got to say Upton...

The San Francisco 49ers require some depth at defensive tackle after Kevin Givens sustained a pectoral injury that will force Givens to “be out for a while,” per Kyle Shanahan. Bruce Hector was a recent addition, but he only saw limited action with the New York Jets the previous two seasons. Because of this, the team worked out four defensive tackles on Wednesday afternoon.

Shakel Brown, who spent time on the Niners’ practice squad in 2024, was one of the tryouts. Brown, 6’3″, 295 pounds, was an undrafted free agent from the 2023 NFL Draft class.

Michael Dwumfour, who signed...

It’s not unusual for teams to have several transactions during training camp. Battling attrition can be challenging when you’re trying to balance injuries, rest, and proper reps; it’s one of the many tasks head coaches have to juggle.

The San Francisco 49ers are no strangers to injuries, which is why we’ve seen so many roster moves in recent weeks. Not all transactions are due to poor player performance. Sometimes it’s not a fit, other times it’s culture-related, while injuries, of course, are another reason.

One man’s trash is another man’s treasure. A trio of 49ers who were recently released will...

You can’t read a training camp report about the San Francisco 49ers without the first or second sentence involving second-year pro Ricky Pearsall. By all accounts, Pearsall is thriving in practice as he continues to build rapport with quarterback Brock Purdy.

However, Pearsall isn’t the most important player from the Niners’ 2024 draft class. That would be cornerback Renardo Green, who has an opportunity to be a critical piece in a defense in search of a top cornerback. Deommodore Lenoir is likely shifting to a “new” role where he’ll live on the perimeter instead of primarily playing in the nickel...

The NFL sent out a memo to teams on Tuesday morning, causing San Francisco 49ers tight end George Kittle to crash Fred Warner’s interview on NFL Network to “air a grievance.”

The memo prohibits teams from giving players any form of ammonia, including ammonia capsules, inhalers, ammonia in a cup, or any form of smelling salts. And that isn’t just during game time. Clubs are not permitted to supply ammonia during pregame activities, halftime, in the locker room, or on the sideline at any point.

As Warner was being interviewed, Kittle approached the set on NFL Network, saying, “I honestly...
