For 26 snaps on Thursday night, Kurtis Rourke looked like exactly what the 49ers hoped they were getting when they used a seventh-round pick on him in 2025. Then a hit to the ribs sent him to the hospital, and suddenly the most encouraging storyline of the preseason opener came with an asterisk.
But even in a limited, injury-shortened look, Rourke did enough against the Titans to force a conversation the 49ers probably weren't planning to have this early: what do they do with three quarterbacks they actually like?
A Debut Worth Talking About
Rourke got the start with Brock Purdy and Mac Jones given the night off. It put him in a straight competition with fellow backup Adrian Martinez for reps behind the regulars. He didn't just win that competition -- he made it look easy.
Rourke finished 12-of-14 for 101 yards and added three carries for 14 yards, good for a 96.7 passer rating, before the injury cut his night short on a quarterback draw near the goal line. He extended a scoring drive with a 32-yard sideline strike to wide receiver De'Zhaun Stribling, slipped a free blitzer for a scramble that had shades of a certain other 49ers quarterback's improvisational style, and generally looked comfortable directing an offense for the first time since December 2024, when a torn ACL ended his final college season at Indiana.
It was enough to draw a public compliment from star offensive tackle Trent Williams, of all people, mid-broadcast. It was also enough for more than one outlet covering the game to reach for the same comparison: this looked a lot like Brock Purdy's early tape.
That comparison isn't just a lazy narrative hook. There's an actual decision buried underneath it.
The 2022 Parallel
Go back to August 2022. The 49ers had just given Nate Sudfeld a fully guaranteed contract to be their No. 2 quarterback behind starter Trey Lance, with Jimmy Garoppolo eventually being brought back. Purdy, the very last pick in that year's draft, wasn't supposed to be a major part of the conversation. He beat that expectation anyway, and the 49ers found themselves staring at a decision on cutdown day: trust that a seventh-round rookie would clear waivers and land safely on the practice squad, or burn a 53-man roster spot to guarantee they wouldn't lose him.
They chose the second option. Kyle Shanahan later admitted the team had picked up intel that at least two other clubs were ready to submit a waiver claim on Purdy if he was exposed. So San Francisco kept three quarterbacks on the active roster to start that season rather than risk it. The rest of that story doesn't need to be retold here.
Now look at where the 49ers sit heading into the 2026 stretch run of the preseason. Brock Purdy is entrenched as the starter. Mac Jones is locked in as the veteran backup. That's a quarterback room that, on paper, only needs one more arm on the practice squad for camp depth. Except Rourke just gave the coaching staff a real reason to wonder whether he'd survive waivers if they tried to sneak him through.
Why Rourke Isn't a Normal Case
There's a wrinkle that makes Rourke's situation a little different from a typical third-string arm fighting for a practice squad spot: he's technically in Year 2, but Thursday was his first taste of NFL action. Rourke spent his rookie season on the Non-Football Injury list rehabbing that ACL, which meant no practice reps—except when he briefly had his practice window opened—no game reps, nothing but rehab work and meeting rooms.
Roster-wise, he's a second-year player. Developmentally, he's closer to a true rookie who just happened to skip an entire calendar year of on-field NFL experience.
That distinction matters for how the 49ers think about exposure risk. A rookie who flashes in the preseason opener is an obvious trade-deadline-for-other-teams type of watch-list name around the league. A quietly buzzed-about talent who missed his entire first year and is only now putting tape out into the world is arguably an even juicier flier for a quarterback-needy team scanning the waiver wire -- precisely because so few people had eyes on him before Thursday.
If evaluators around the league watched that Titans tape and saw the same thing Williams saw in real time, the 49ers may not be willing to bet that Rourke slides through unclaimed.
The Roster Squeeze
None of this happens in a vacuum. Carrying three quarterbacks on the 53-man roster means carrying one fewer body somewhere else -- along the offensive or defensive line, at a skill position, on special teams. It's exactly the tradeoff Shanahan and John Lynch weighed in 2022, and it's the same tradeoff that resurfaces anytime the quarterback room outperforms its roster spot allotment.
San Francisco has already lived through the alternative version of this problem this past season, when Purdy's injuries forced Martinez into a recurring practice-squad-elevation shuffle just to keep a healthy body on the sideline as the emergency arm -- a workaround that comes with its own rules and limitations under the league's game-day elevation system.
Keeping Rourke on the 53 solves that problem before it starts. It also costs a roster spot the 49ers might want elsewhere on a team that's supposed to be building toward a Super Bowl push, not stashing insurance policies at a position that's currently about as settled as it's been in years.
It's one preseason performance, cut short by injury. But it was against a team that decided to play its starters. Nobody in the building is going to overreact to 26 snaps. But the 49ers have been here before, and they know exactly how it worked out the last time a late-round quarterback made the decision harder than it was supposed to be.
Rourke's rib injury will determine a lot of what happens next -- but the roster question he raised isn't going away just because he's day-to-day.
