Core Event: Knee Injury in Week 4 Victory over the Broncos
During the fourth quarter of the San Francisco 49ers’ 24-14 win over the Denver Broncos on October 4, 2026, fullback Kyle Juszczyk hyperextended his right knee after a low-tackle by Broncos cornerback Jahdae Barron. Trainers assisted the 35-year-old 10-time Pro Bowler off the field, and he did not return.
Background & Context
Juszczyk is a central piece of Kyle Shanahan’s offense, serving as the lead blocker for quarterback Brock Purdy, running back Christian McCaffrey, and wide receiver Deebo Samuel. He also functions as a reliable short-yard receiver, recording four catches for 55 yards and a touchdown through the first four games of the 2026 season. His versatility has earned him three consecutive All-Pro honors (2023-2025) and a reputation as one of the league’s best fullbacks.

Official Statements & Responses
Head coach Kyle Shanahan said the early evaluation suggested a sprain and that the ACL “appeared intact.” “Juice, we don't know for sure,” — Kyle Shanahan, head coach
ESPN insider Adam Schefter reported that the initial tests showed hyperextension and that an MRI was scheduled for the following day. After the MRI, Schefter confirmed the diagnosis of a sprain and bone bruise and projected a 2-3-week recovery.
Conflicting Reports & Gaps
- Duration of absence: Newsweek, USA Today, and NBC Sports cite “a couple of weeks,” while Rotowire and the NFL Network’s Rapoport describe the outlook as “several weeks.” Sports Illustrated’s coverage aligns with the 2-3-week estimate. No outlet has provided a definitive return date beyond the projected October 25 or November 8 windows.
- Potential roster move: Rotowire mentioned the possibility of placing Juszczyk on injured reserve, but no official decision has been announced.
Why It Matters
Juszczyk’s blocking and short-yard receiving are integral to the 49ers’ balanced attack. His absence comes ahead of a matchup with the Seattle Seahawks, whose defense ranks among the league’s best. Without his lead-blocking on the edge and his ability to convert critical third-down catches, the 49ers may need to adjust protection schemes for Purdy and rely more heavily on other backs and tight ends.
