The San Francisco 49ers opened their 2026 preseason with a 19-13 loss to the Tennessee Titans at Levi’s Stadium, highlighted by standout rookie wide receiver De’Zhaun Stribling’s stellar debut and a concerning rib injury to quarterback Kurtis Rourke.
August 14, 2026. While the scoreboard favored Tennessee on Thursday night, the underlying metrics and personnel usage paint a far more complex picture for head coach Kyle Shanahan’s squad as they march toward the season opener in Melbourne, Australia.
Fantasy & Market Impact
- Wide Receiver Rotation: With Mike Evans, Deebo Samuel, and Christian Kirk kept on the sideline, Stribling’s dominance against Tennessee cornerback Cor’Dale Flott alters the projected depth chart hierarchy heading into Week 2 of the preseason.
Stribling’s Masterclass Outshines the Box Score
For a team missing marquee names on the outside, the audition was wide open. Wearing the No. 15 jersey recently vacated by Jauan Jennings, the rookie racked up seven receptions on eight targets before the midway point of the second quarter.
But the numbers only tell half the story. Stribling consistently won leverage battles against Titans cornerback Cor’Dale Flott, highlighted by a 32-yard vertical grab where he tracked a deep ball down the right sideline and secured it through contact. As Stribling noted postgame regarding the play, “I had a man-on-man matchup. He was playing a little off, 3 yards away. I kind of just stepped on his toes with pure speed. (He) had his hands ready, so I swiped his hands down, dug out, looked for the ball.”
The Rourke Dilemma and Quarterback Depth
Behind center, Kurtis Rourke engineered a sharp start before disaster struck. The 2025 seventh-round pick, returning from an ACL repair, completed 12-of-14 passes for 100 yards while displaying impressive dual-threat mobility. However, a punishing hit on a run to the 1-yard line altered the trajectory of his evening.
According to coach Kyle Shanahan via the Mercury News, initial X-rays at the stadium did not reveal a fracture, but Rourke was sent to the hospital at halftime due to severe breathing difficulties. With Brock Purdy and Mac Jones resting, Adrian Martinez stepped in to finish the contest, going 16-of-30 for 159 yards. Had Martinez gone down, the 49ers were prepared to deploy tight end Brayden Willis on emergency handoff duty—a stark reminder of how fragile NFL preseason depth charts can be.
Roster Construction and Front-Office Outlook
| Quarterback | Comp / Att | Yards | Key Status / Notes |
|---|---|---|---|
| Kurtis Rourke | 12 / 14 | 100 | Exited with rib injury; hospital evaluation |
| Adrian Martinez | 16 / 30 | 159 | Stepped in relief; managed second-half offense |
With Shanahan and George Kittle managing their respective health timelines ahead of the global opener against the Los Angeles Rams on September 10, the emergence of cost-controlled rookies like Stribling provides vital financial and tactical flexibility.
The Road Ahead to Melbourne
As the 49ers pivot toward their next preseason fixture, the medical room will dictate the narrative just as much as the tactical whiteboard.
Yet, the bigger takeaway remains etched in the development of the youth movement. Stribling has forced his way into the offensive game plan, giving Shanahan a dynamic weapon who can stretch the seam and win 50-ball matchups. How that translates against starting-caliber defensive schemes will define the next phase of San Francisco’s summer.
