Coach Kyle Shanahan Reveals Reason for 49ers' Loss to Jaguars: “Without Him, There’s No Chance for the 49ers”

San Francisco, September 29, 2025

The San Francisco 49ers suffered their first loss of the 2025 season, falling to the Jacksonville Jaguars with a score of 21-26 in Week 4. While many focused their criticism on the mistakes of the offense and QB Brock Purdy, head coach Kyle Shanahan offered a different, candid perspective: the absence of Nick Bosa was the key reason the team lost control of the game.

Kyle Shanahan Breaks Down 49ers Close Loss to Jaguars | Press Pass

The 49ers’ top defensive star suffered a severe injury in the previous game and was forced to sit out for the rest of the season. This was a major blow for San Francisco, as Bosa has been a cornerstone of their defensive system, consistently pressuring opposing quarterbacks. Without him, the 49ers’ defense lacked its usual potency and was easily exploited.

In the post-game press conference, Shanahan spoke with a tone of deep regret:

“Without him, the 49ers faced a lot of difficulties. He’s a critical part of this team and always makes a difference on the field. That said, we have to find ways to adapt, trust in the collective, and let other players step up to fill the void.”

The game against the Jaguars was clear evidence. The 49ers’ defense generated limited pressure, allowing Trevor Lawrence more time to deliver decisive passes. The Jaguars capitalized fully on the gaps in the defensive line, scoring in critical moments and controlling the game’s tempo.

Experts note that while the 49ers still have a disciplined defense, losing Bosa means they lack the star capable of turning the tide with a single play. This forces Shanahan to seek alternatives, from rotating players to adjusting the blitz system, but the void left by Bosa is undeniably significant.

This loss serves as a reminder that the 49ers need not only a steady quarterback but also a healthy defensive cornerstone to go far in the season. And with Shanahan’s admission, San Francisco now faces the daunting challenge of learning to cope without Nick Bosa.

49ers Locker Room Leak: The Moment George Kittle Whispered to Jake Tonges That Left the Team With Questions — Tension Rising Ahead of the NFC No. 1 Showdown vs. the Seahawks
Santa Clara, California — As the entire NFL turns its attention to the looming NFC No. 1 showdown between the San Francisco 49ers and the Seattle Seahawks, a seemingly small moment at a 49ers practice has unexpectedly sparked big questions inside the locker room. George Kittle — the emotional heartbeat of the team — was spotted whispering privately with Jake Tonges in a corner of the field, long enough and serious enough to draw noticeable attention. On the eve of a game that could define the regular season, an already intense atmosphere suddenly felt even more delicate. According to those in attendance, Kittle deliberately pulled Tonges aside while the rest of the roster went about its usual drills. There was no joking, no familiar laughter. Just two tight ends standing close, locked in a quiet exchange that lasted far longer than a casual sideline chat. One team source described the scene bluntly:“I saw the two of them talking alone in one corner of the field for a long time. Nobody on the team went near them. It looked serious — like a conversation you immediately know isn’t meant for everyone to hear.” That detail alone was enough to stir whispers throughout the building. With the stakes this high, every movement carries weight — and right now, all eyes are on Kittle’s health. The All-Pro tight end has been dealing with an ankle injury, and while his return to the practice field was encouraging, the central question remains unanswered: will he be physically ready to play in one of the most important games of the season? At first glance, the private exchange raised speculation of tension or internal concern. But viewed in proper context, the moment tells a different story. Kittle isn’t just a star — he’s the standard-setter. He’s the voice that demands urgency, especially when the calendar turns toward January. Those familiar with the situation suggest the conversation carried no hint of conflict. Instead, it reflected playoff reality. Kittle wants to play — badly. Even if he isn’t at full strength, his mindset is clear: if there’s any way to be on the field, he intends to be there. At the same time, he understands the truth of the depth chart. If his body doesn’t respond, the next man up is Jake Tonges — a player who has already proven he can handle the moment. For Tonges, the exchange wasn’t pressure — it was preparation. When one of the league’s elite tight ends chooses to speak with you privately before a game of this magnitude, it’s a sign of trust. Tonges knows his role: be ready if called upon, and be ready immediately. Inside the 49ers’ locker room, the moment didn’t fracture anything. It clarified things. This isn’t a team that hides realities or avoids hard conversations. When a division title and the NFC’s top seed are on the line, honesty becomes non-negotiable. If you can play, you play. If you can’t, you prepare the man beside you to step in. If the locker room felt a shift, it wasn’t panic — it was pressure. The pressure of a team carrying Super Bowl expectations, where even the quietest moments matter. Sometimes the most revealing snapshots of a season don’t come from press conferences or stat sheets. They come from whispered words — spoken softly enough to stay private, yet heavy enough to be felt by everyone around them.
