The San Francisco 49ers started their NFL season in impressive fashion with a 3-0 record, standing among the few teams that remained undefeated despite early-season challenges. However, the squad is now dealing with the loss of one of their stars and key contributors, Nick Bosa.
The 49ers felt the blow of losing their star edge rusher Bosa for the remainder of the 2025 season after he suffered a torn right ACL. All-Pro linebacker Fred Warner tried to capture the impact of Bosa’s long-term absence when speaking to reporters at 49ers practice on Wednesday in Santa Clara.
“I’m sick. I’m so sick for him, because he knows what it’s like to go through that process – a recovery from that injury, which I know he’s fully capable of,” Warner said when asked about team morale. “But that doesn’t make it any easier. Obviously, it’s a huge deal for our team. But we move forward.”
“I hate to say ‘next-man-up mentality,’ because you can’t just replace him with one player. But the mission is still the same. We’re going to find a way to get one win this week, and we’ll figure out the rest later.”

Bosa had been in a groove
Bosa was on a tear before suffering his third ACL tear (the third of his career dating back to high school) during San Francisco’s 16-15 Week 3 win over the Arizona Cardinals at Levi’s Stadium.

Beyond Warner’s remarks, the injury is especially hard for a passionate competitor like Bosa. Warner spoke with him and confirmed the star lineman is as devastated as everyone else. Understanding Bosa’s injury history makes the absence that much harder to absorb.
“I sat and talked with him right when he found out,” Warner said. “We spoke about it, and obviously, he’s devastated; we’re devastated for him. We’re just praying for him, and whenever he gets the surgery, it goes well and his recovery is smooth.” Warner and his teammates know that the 49ers’ star defensive lineman will return and come back stronger than ever next NFL season.
