Sunday gives the 49ers a clean chance to find out what they really are.
Denver isn’t Seattle, but it isn’t a soft landing either. The Broncos bring a disruptive defensive line, an athletic quarterback, and a veteran coach who can make life messy if a team gets sloppy. That makes this matchup feel like a marker game, the kind that can reveal more than the scoreboard ever will.
One of the biggest tests starts up front. The 49ers’ offensive line has yet to allow a sack, but this is a different challenge than the ones they’ve already handled.
Connor Colby and the interior group have been better than expected, though the Broncos’ front is a step up from Miami or Arizona. And next week, Seattle figures to be even tougher.
The pass rush pressure also connects to how the 49ers operate without their top receivers. Mike Evans might not play, which puts even more weight on the rest of the offense.
Brandin Cooks is set to make his 49ers debut on Sunday, but the 49ers will need more than that. George Kittle, Christian McCaffrey and even a little Kyle Jusczyzk will have to help keep the chains moving, especially against a Denver defense that pairs strong coverage with linebackers who can be attacked.
That same Broncos defense can also force offenses into ugly, patient football. Kansas City showed the formula in Week 1 by making Denver miss 26 tackles, and that’s the kind of blueprint the 49ers will try to borrow if they want to establish the run.
There’s also the question of whether they can keep Bo Nix contained without Nick Bosa. Nix is not as polished as Matt Stafford, but he is the most athletic quarterback the 49ers have seen so far, and he has enough juice to flip a game when things click. He can be maddeningly inconsistent, but he can also win on his own if he’s allowed to escape the pocket and play on his terms.
That puts even more pressure on the secondary, which has its own difficult assignment. Jaylen Waddle is good to go, and Courtland Sutton is no easy cover. One coverage bust on the back end could be enough to wake up Nix, especially if he’s able to start stepping up in the pocket instead of being forced backward.
The 49ers’ own offensive line is part of the story, too. Klay Kubiak pointed to Talanoa Hufanga’s big red zone sack against Matthew Stafford in Denver’s win over the Rams as a reminder of how aggressive Vance Joseph’s defense can be. Hufanga came off the edge from Stafford’s blind side and was left unblocked.
“He knows when to call his shots,” Kubiak said of Joseph. “He knows when to be aggressive and come after the quarterback.
That group’s been playing together for a while. And when they call those blitzes, they usually work.”
For the 49ers, that means the margin for error stays small. Part of their early success has been simple: they haven’t been beating themselves.
There’s also no shortage of individual names worth tracking. Osa Odighizuwa remains the clear headliner on the defensive side, but the 49ers need at least one more player to pop from their nine-man rotation.
Rookie Gracen Halton could be that guy. A fourth-round 2026 NFL Draft pick, Halton is starting for the third straight game, already has a couple of tackles for loss, and looks like he may be moving toward more impact plays.
On the injury front, the 49ers added a rookie to the report, while Dante Pettis is dealing with a calf issue. Evans is listed as a game-time decision because of a rib injury.
Shanahan said of that situation, “he’s definitely a lot tougher than me. Hopefully, he’s got a shot.”
And if the game comes down to the final kick or one last mistake, even that part could matter. One preview picked the Broncos to win 27-26, pointing to the possibility of a flat 49ers performance and the risk of another Eddy Piñeiro extra-point miss in a close one.
Shanahan, meanwhile, made clear how he approaches a week like this one. He said he doesn’t try to manufacture belief with speeches.
“All of the above. Depends where we’re at at the time, where the team’s at.
It changes every week. You can have it come off a huge win and people question the team you’re playing.
That happened to us in Week Two. A big win versus the Rams in Australia.
Then people have us as huge favorites and stuff the next week versus Miami. I don’t try to talk people up because I don’t think people believe words.
I think people believe what they see and I can’t talk people up unless I believe it. So, I usually try to find it in the tape and show people what people can be and what they need to be worried about.
It’s something I usually do earlier in the week. I think that fear to fail or respect of people, however you want to word it, is what gets you to work a certain way.
The whole goal is to work hard enough so you don’t feel that way, and to me, the goal is to not feel that way by Saturday night so you go into Sunday confident. And if you feel that way on Monday, I usually think you’re in trouble.
You’ve got to earn that. It’s got to be real, and that’s through the work you do and the preparation.
You prepare the right way if you respect an opponent and I believe we respect whoever we’re playing every week.”

49ers Face A Mac Jones Decision Fans Cant Ignore
The 49ers have been getting calls on Mac Jones, but the buzz around the backup quarterback is not changing the teams view of him. ESPNs Dan Graziano reported that San Francisco sees Jones as important insurance behind Brock Purdy, which helps explain why the club is expected to keep him rather than move him before the NFL trade deadline.
San Francisco has reportedly heard from multiple teams, but the asking price remains steep enough that a deal may not come together. Jones value to the 49ers is rooted in what he already showed in a starting role last season, when he filled in for eight games and helped the team go 5-3, giving the front office a reason to treat him as more than just a spare arm.

49ers Week 4 Outlook Suddenly Hinges On One Late Decision
A late rib injury has turned Mike Evans into one of the biggest pregame variables on the 49ers Week 4 radar, with the veteran wide receiver now listed as questionable for Sundays matchup against the Denver Broncos. Evans was hurt in Week 3 and is being treated as a game-time decision, leaving San Francisco to wait until roughly 90 minutes before kickoff for the official word.
Evans has made it clear he wants to suit up, and his history of playing through similar injuries only adds to the uncertainty around how much the 49ers can count on him. For a team trying to keep its offense on schedule against a Broncos defense that can make every possession matter, his availability could shape the way San Francisco approaches the game from the opening drive on.

49ers Linked To A Draft Back For Life After Christian McCaffrey
Jahiem Whites 2026 season at North Texas has put him on the radar as a potential mid-round pick in the 2027 NFL Draft, and the skill set is easy to see for a team like the 49ers. He has flashed the kind of elusiveness, vision and burst that tend to play well in San Franciscos offense, especially for a back who can create with the ball in his hands and keep defenses honest on the perimeter.
For the 49ers, the appeal is less about asking White to carry a heavy weekly load and more about the idea of a change-of-pace runner who fits alongside bigger personnel decisions at the position. His profile suggests a player who can complement a more physical inside option, which makes him the kind of draft name worth tracking as the process moves forward. [Read more 🡒]
